Description

Schedule display method and device

The present invention relates to editing and displaying personal schedule information by using a computer system. A user can record his schedule through an electronic notebook instead of a normal notebook.

Conventional electronic notebooks display this schedule by a time axis. For example, in the "Schedule+" software developed by Microsoft Corporation, a schedule display screen is shown in FIG. 2, in which the time axis and schedule display area are used to display schedule attributes and schedule content. The schedule display area is parallel to the time axis, and the schedule content is displayed in the schedule display area at positions corresponding to the start and end time points of the schedule events.

The above-mentioned prior art provides a desirable function for recording calendar events, but there are several problems as follows:

(A) When writing a record, most users usually record calendar events in a continuous manner, writing the time before the record. The timeline is used as a reference in planning the schedule. A regular schedule displayed in a computer is inconvenient for usual habits. The entire schedule time allocation can be displayed on the time axis, and the idle time interval between two schedule events still occupies a certain display area in the schedule display. This results in a display screen that is too long, so that the schedule needs to be browsed by scrolling the screen from time to time. All schedule event data cannot be displayed consecutively. This display space cannot be effectively used for more information.

(B) There are no special displays designed to differentiate scheduled events. All schedule events are displayed in a schedule display area, which makes it easy for users to understand the attributes of schedule events.

In order to solve the above problems, the present invention provides a schedule display method, which can edit and display personal schedule information by using a computer system, the method includes:

The first step is to construct a schedule display table with M columns and N rows in the memory of the computer, wherein the schedule data of one day is recorded in the cells of the schedule display table, and each cell records a A pointer to the temporary storage address of the schedule data, a schedule event number before the working time, a schedule event number after the working time, and the start position, end position and height value of each schedule event;

The second step is to update the schedule display table by judging the editing or browsing behavior from the user, so as to manage the schedule display table;

The third step is to check the modification part in the schedule display table, which can judge whether the schedule display table needs to be updated according to the editing or browsing behavior from the user;

The fourth step is to draw a time axis with a schedule time attribute according to the modified part in the schedule display table, draw two adjustment buttons for working hours and a display switch of the sub-schedule display table; and

The fifth step is to prepare a main schedule display area listing all schedule data within working hours and a secondary schedule display area listing all schedule data before and after working hours according to the updated schedule display table.

Correspondingly, the present invention provides a schedule display device, which can edit and display personal schedule information by using a computer system, including:

A schedule display table with M columns and N rows constructed in the memory of the computer, in which each cell stores a display record of a day and a schedule display table of a day, and the display record of the day includes a schedule display indicating the day A pointer to the address of the table, the number of calendar events before and after the working time, and a pointer representing the temporary storage location of the schedule data, and the schedule display table of the day stores the start position, end position and altitude value of each schedule event The data.

A schedule display table management part, which is used to judge the type of behavior from the user as editing, browsing or modification through the input content of the input device, and is used to perform corresponding insert, modify, delete, and reload operations of the schedule display table;

A modification area checking section for searching the schedule display table and calculating the modification portion in the display area according to the specific display mode and actions from the user by the input content through the input device to judge whether the time axis and the main and sub time display areas are It needs to be changed by editing and browsing the schedule display table or modifying working hours;

a schedule display section for obtaining a pointer of schedule data of a date to be displayed based on a specified display mode and a searched schedule display position table, and judging the schedule by reading the schedule data from a schedule date storage section using the pointer whether the event is within working hours, detects any overlap of calendar events, and displays the content of the calendar events in the primary and secondary calendar display areas respectively; and

A time axis display section for drawing the time axis according to the working time set by the user, checking whether there is any overlap of the modified schedule events, drawing a schedule time attribute, and drawing two working time adjustment buttons and a sub-schedule display area display switch.

The schedule display device according to the present invention can provide two display modes, namely, a vertical mode and a horizontal mode. In a mode designated by the user, a corresponding schedule display table is constructed in a memory to manage and display necessary information. After the user edits, browses or modifies the schedule display table, the schedule display table management part will update a new schedule display table, and the modification area checker will check the modified part in the display area.

The purpose of the schedule display apparatus according to the present invention is to process schedule data in a computer system by constructing a schedule display location table in a memory to manage and display schedule information. The schedule display device according to the present invention can provide vertical and horizontal display modes, so that the user can quickly and conveniently edit and browse the schedule. In the vertical display mode, a time axis is arranged vertically and parallel to the main schedule display area. In the horizontal display mode, a time axis is placed horizontally above the main schedule display area. In the vertical display mode, schedule data in the main schedule display area is displayed at locations corresponding to times of schedule events. In the horizontal display mode, the schedule data in the main display area are successively displayed in order. In the vertical and horizontal modes, the schedule data in the sub-schedule display area are successively displayed in order. According to the working hours set by the user, the schedule events within the working hours are displayed in the main schedule display area, and the schedule events outside the working hours are displayed in the secondary schedule display area. In addition, there are two working time adjustment buttons and a display switch for the sub-schedule display area in the display screen. One adjustment button of the working time is used to adjust the start time point of the working time, and the other adjustment button of the working time is used to adjust the end schedule of the working time. The display switch of the sub-schedule display area is used to control whether to display the sub-schedule display area.

FIG. 1 is a block diagram showing a schedule display device according to one embodiment of the present invention. In Fig. 1, reference numeral 10 denotes an input device constituted by a keyboard and a mouse, wherein the keyboard is used for inputting schedule data, and the mouse is used for adjusting the start and end time points of working hours, indicating to be Modified calendar event and moving that calendar event. Reference numeral 40 denotes a schedule editing section having a schedule editor for editing contents of scheduled events. By using the schedule editor, the user can change the time period of the schedule event, confirm the schedule event, delete the schedule event, set the schedule content. Reference numeral 31 denotes a schedule display list. The schedule display table is an array of M columns and N rows. In a typical example, M is 7 and N is 6. In this example, the schedule display table has 42 cells in total. A one-day display record for one day and a one-day schedule display table are stored in each cell. The display record for the day includes a pointer indicating a temporary storage location of the memory storing the schedule data, and a schedule display list indicating the day for storing all the schedule event data. Reference numeral 50 denotes a schedule data storage area which stores schedule data. The display record of the day also includes two numbers cLeft and cRight, respectively representing the number of calendar events before and after the working time. The day's schedule display table stores the start time point, end time point and altitude value of the schedule display area for each schedule event. Reference numeral 30 denotes a schedule display management section for judging the type of action according to the position of the mouse click. If the mouse moves to the browsing key or the scroll bar and clicks the left button, then this behavior is judged as schedule browsing behavior. If the mouse moves to a schedule display area without a schedule event and clicks its left button, this behavior is judged as a schedule adding behavior. On the other hand, if the mouse is moved to a schedule display area with a schedule event and its left button is clicked, then this behavior is judged as a schedule modification behavior or a schedule moving behavior. If the position where the mouse is released is different from the position where the mouse is clicked, the behavior is judged as a schedule move behavior. Otherwise, the action is judged as a schedule modification action. The schedule editor of the schedule editing section 40 is activated to edit the content of the schedule event. After the editing is finished, the schedule display table management section 30 updates the schedule display table 31 . When a calendar event is moved or edited, this display area will change accordingly. The modification area checking section 21 checks the modification area in the display area. Then the time axis display part 22 and the schedule display part 23 respectively show the time axis and the schedule data, by searching the number of schedule events before and after the working hours, the start time point, the end time point and the altitude value of the schedule display area are used to modify the schedule event.

The schedule display table management section 30 is the basic control section of the present invention. As shown in FIG. 1 , the schedule display table management section 30 manages the schedule display table 31 stored in the schedule data storage area 50 . In the schedule display table 31, a start time point, an end time point and an altitude value of each schedule event are recorded, so that a modified part of the schedule can be easily detected and the schedule data can be directly displayed.

FIG. 3 is a diagram showing the data structure of the schedule display table 31 according to one embodiment of the present invention. A schedule display table with M columns and N rows is constructed in the memory of the computer. A display record for one day and a schedule display table for one day are stored in each cell of the schedule display table 31 . The display record for the day includes a pointer (ptToDayTable) indicating the table in which all the schedule data for the day is stored, a pointer indicating the temporary storage location of the schedule data (ptToDayStorage), a number indicating the number of items of the schedule event before the working time (cLeft), and a number (cRight) representing the item number of the calendar event after business hours. The day's schedule display table includes the start time point, end time point and altitude value of each schedule event.

In a typical example, the schedule display table 31 has 7 columns and 6 rows. There are totally 42 cells in the schedule display table 31 for storing schedule data of 42 days.

FIG. 4 is a schematic flowchart showing a processing portion of the schedule display table management section 30 according to an embodiment of the present invention. Step S71 judges whether there is a schedule browsing behavior, and if the judgment result is "No", then the process goes to step S72 for determining the type of schedule editing behavior. In step S72, the type of schedule editing behavior is determined. If the schedule editing action is to add, the process goes to steps S73 and S74 for searching for an appropriate position in the schedule display and inserting a new schedule event, respectively. If the schedule editing action is deletion, the process goes to step S75. If the schedule editing action is modification, the process goes to step S76. In step S76, the height of the display range is changed. If the schedule editing action is move, the process goes to step S77. Step S77 is for moving a schedule event, wherein an old schedule event is firstly deleted, and then a new schedule event is added. If the action does not belong to one of adding, deleting, modifying and moving, the process goes to "end". If the result in step S71 is "YES", the process goes to step S78 for judging whether the data to be browsed is in the displayable range. If the data to be browsed is not in the displayable range, the process goes to step S80 for calculating a new displayable range. After the new displayable range is calculated, the process goes to step S80 for searching each schedule data and calculating a display record. Then the process goes to step S82, and all the schedule display position tables are loaded in the monthly schedule display table. The process then reaches "end". If the data to be browsed is within the displayable range, the process goes to step S79 for judging whether the working hours are changed. If the judgment result is "No", the process reaches "End". If the judgment result is "Yes", the process goes to step S83 for calculating the start and end time points of the work time on a time axis. The process then goes to step S84 for counting the number of calendar events before and after the new working time, and modifying the display record.

FIG. 5 is a schematic flowchart showing the processing steps of the modified area checking section 21 according to one embodiment of the present invention. When the schedule events during working hours occupy a larger area than the display area, you need to use the scroll bar to view the schedule in the main schedule display area. In vertical mode, the time axis is set vertically, and the height value of the calendar event corresponds to the time period. Therefore, when moving the scroll bar in vertical mode, the time axis and display area are moved simultaneously. In horizontal mode, the time axis is set horizontally above the display area, so when the scroll bar is moved, only the schedule display list is moved. The schedule data before and after the working hours are continuously displayed in the sub-schedule display area. In the sub-schedule display area, the schedule data is displayed in a horizontal pattern.

Referring now to FIG. 5, a flow chart of the modification area checking section 21 according to an embodiment of the present invention will be described below. Step S90 checks whether there is a modified part. If a modified portion is generated from schedule editing, the process goes to step S100 to execute steps S101-S114. If a modified part is generated from scrolling the main schedule display area, the process goes to step S120 to perform steps S121-S128 for searching the time axis and the modified part in the main schedule display area. If a modified part is generated from scrolling the sub-schedule display area, the process goes to step S140 to execute steps S141-S147 for searching the modified part in the sub-schedule display area. Also, if there is no modified part, the process goes to step S150 to perform other actions.

Step S101 divides the schedule editing behavior into five categories: schedule deletion/addition in vertical mode, schedule movement in vertical mode, schedule deletion in horizontal mode, schedule addition in horizontal mode, and schedule deletion in horizontal mode schedule moves, etc. Steps S102-S105 check the modified portion of the main schedule display area in the vertical mode, and steps S106-S113 check the modified portion of the main schedule display area in the horizontal mode. In the horizontal mode, step S113 needs to be executed for checking the modified part in the time axis. In vertical mode, modifications to schedule additions or deletions are limited to the start and end positions of a schedule event. Step S102 is used to calculate a start position "s" and an end position "e" in the time axis for a target calendar event. When a calendar event is moved, step S103 checks whether the target calendar event and the source calendar event are on the same screen. If the result is "Yes", the process goes to step S104 for calculating the combined start position "s" and end position "e" of a target schedule event and a source schedule event. If the result is "No", the process goes to step S102. Step S105 transforms the positions "s" and "e" into coordinates "sy" and "ey". The upper left corner of the display area is set as the origin, and its coordinates are (0, 0). Step S114 calculates the coordinate range (0, sy, x, ey) of the modified part of the main schedule display area in the vertical mode, where "x" is the width of the main schedule display area, and calculates the coordinate range of the modified part in the time axis (0, sy, x1, ey), where "x1" is the width of the time axis.

In addition, in horizontal mode, when a calendar event is deleted, the calendar events after the deleted calendar event will be affected. By searching the schedule display table 31, steps S106 and S107 respectively calculate the height "sy" of the start position of the target schedule event and the height "ey" of the end position of the target schedule event in the display area. The schedule addition is completed by the user inputting schedule data in the blank area of the schedule display list. In horizontal mode, the blank space is below all calendar events. Therefore, when adding a scheduled event in the horizontal mode, step S108 calculates the height "sy" of the start position of the target scheduled event in the display area by searching the display position table. Step S109 calculates the height "ey" of the end position of the target scheduled event in the display area. In addition, when a calendar event is moved, step S110 judges whether the source calendar event and the target calendar event are on the same display screen. If the result is "Yes", the process goes to step S111 to calculate the combined display area occupied by the source and target scheduled events. If the result is "No", calculate "sy" and "ey" similarly to schedule deletion. The time axis in horizontal mode is modified in response to modification of the time period for the calendar event. Therefore, after detecting the modified portion in the main schedule display area in the horizontal mode, step S113 performs corresponding editing similar to the vertical mode and detects the modified portion in the time axis. In the horizontal mode, for the modification in the main schedule display area and the time axis, step S114 calculates the coordinate range (0, sy, x, ey) of the modified part in the main schedule display area, and the coordinate range of the modified part in the time axis (sy1, 0, ey1, y), wherein x is the width of the main schedule display area; y is the height corresponding to the time period in the time axis; sy1 and ey1 correspond to "sy" and "ey" calculated by step S113 "value.

When the main schedule display area is scrolled, steps S121-S128 process the checking for modification. After searching the schedule display location table 31, step S121 obtains a display record "i" of the first schedule event in the main schedule display area. Step S122 judges that the display record "i" is within the working hours, so as to judge whether scrolling can be performed. If it is judged that scrolling can be performed, the process goes to step S123 for judging the type of scrolling. For scrolling in horizontal mode, step S124 judges whether it is scrolling down. If the result is "Yes", the process goes to step S125, which subtracts 1 from "i", which means the previous record. Step S126 sets "n" to the height occupied by the ith display record. For scrolling in vertical mode, the display area is scrolled by a calendar event. Step S127 sets "n" to the height corresponding to the period in the time axis. Step S128 obtains the modified part in the main schedule display area and the time axis. The coordinate range of the modification part in the main schedule display area is (0, 0, x, n) when the schedule display is scrolled down, and the coordinate range is (0, y-n) when the schedule display is scrolled up , x, y), and the coordinate range of the modified part in the time axis is (0, 0, x1, n) when the schedule display is scrolled down in the vertical mode, and when the schedule display is scrolled down in the vertical mode The range of coordinates when scrolling up in the center is (0, y1-n, x1, y1), where "x" is the width of the main schedule display area; "y" is the height of the main schedule display area; and "y1" is the corresponding The height of the period in the timeline.

Next, regarding the process of scrolling the sub-schedule display area, since the sub-schedule display area can only be continuously displayed in the vertical mode, there is no vertical mode scrolling for the sub-schedule display area. Referring to FIG. 5C , after searching the schedule display table, step S131 obtains the record "i" of the first schedule event shown in the sub-schedule display area. Step S132 checks whether the record "i" is the first or last displayed record to judge whether scrolling can be performed, and checks the modified portion in the display area. Step S133 determines the scrolling type of the sub-schedule display area. For scrolling down, step S134 judges whether the record "i" is the first displayed record after the working time. If the result is "yes", then scrolling down needs to skip that working time period. If the number of calendar events before working hours is "cLeft", step S135 sets the record "i" to cLeft, which represents the last calendar event before working hours. If the result is "No", step S136 subtracts 1 from "i", which indicates the previous record. Step S137 sets "n" as the height occupied by the i-th display record, and checks that the coordinate range of the modification part in the secondary schedule display area when the schedule is scrolled down is (0, 0, x, n), and the coordinate range when the schedule display is scrolled up is (0, y-n, x, y), where "x" is the width of the sub-schedule display area, and "y" is the height of the sub-schedule display area .

FIG. 6 shows a schematic flowchart illustrating the processing steps of the time axis display section 22 according to an embodiment of the present invention. In this embodiment, the time axis is a long bar on the display screen, representing a time period of a day, wherein the time period can be divided by 5, 10, 15, 20, 30 or 50 minutes according to user designation. The length of the time axis is displayed by L pixels, corresponding to coordinates from 0 to L-1, so that a time period from 1 to 1440 minutes can be shown. For time "t" (in minutes), it can be located at t1 = t x L/1440. In order to display the schedule in more detail, usually the number of pixels L is larger than the number of pixels that can be displayed by the screen in vertical mode or horizontal mode, thus requiring scrolling of the screen. In vertical mode, a screen of "y" pixels is used as a viewport, and a time unit "u" is drawn by "n" pixels. If in the time axis, "ls" is the start coordinate of the work time, and "rs" is the end coordinate of the work time, then ls=l*L/1440, and rs=r*L/1440. In this case, if a point with coordinate "rs" can be scrolled to the end of the viewport, this makes it possible to scroll the range rs-ls. If we take the upper left corner as the origin of the screen, with coordinates (0, 0), and this origin is denoted by "yo", then yo lies between rs and ls, and for any time "t" coordinates in the time axis Expressed by (tl-ys) x n/u. In addition, for any "yi" point in the viewport, its corresponding time "yt" is expressed by yt=(yo+yi*u/n)*1440/L. When the time axis display section draws a time axis, the time "ti" is calculated from the coordinates in the time axis for the upper left corner of the viewport. ti corresponds to a specific time period if the time period scrolls one time unit at a time. Thus, the time axis can be drawn from the origin of the viewport to the bottom of the viewport, with one unit of time shown by n/4 pixels.

FIG. 6 is a schematic flowchart illustrating the processing steps of the time axis display section 22 according to an embodiment of the present invention. First, step S141 respectively obtains the positions "tl" and "tr" in the time axis, which represent the working time of a day. Step S142 draws a time axis and moves "tl" and "tr" to an appropriate position. Step S143 draws the scale of the time period unit and represents the time value. In addition, step S144 searches for the first display record "i" having an end position value greater than "t1". Step S145 determines whether the start position "s" of the display record "i" is before "t1". If the result is "Yes", the process goes to step S146 to set the value of "s" to "t1". If the result is "No", the process goes to step S147 to determine whether the end position "e" of the display record "i" is after "tr". If the result is "Yes", step S148 sets the value of "e" to "tr". If the result is "No", step S149 calculates the display length of the schedule event "i" as "e-s". After the calculation of the display length is completed, the process goes to step S150 to plot the time distribution corresponding to the display length on the time axis. Step S151 checks whether there is a next scheduled event "i". If the result is "Yes", step S152 checks whether the start position "s" of the display record "i" is before "t1", and if the result is "Yes", the process goes to step S153. If the result of step S152 is "No", repeat steps S147-S151. If the result of step S151 is "No", then this means that there is no next schedule event, or the start position of the next schedule event is after "tr", and the process goes to step S153 to check whether the two ends of the time axis are " tl" and "tr" covered. If the result is "No", the drawing of the time axis is complete. If the result is "Yes", the process goes to step S154 to draw the time end point symbol and the sub-schedule display area switch symbol at both ends of the time axis. Also, in horizontal mode, the time axis is drawn horizontally and the horizontal and vertical coordinates are swapped.

FIG. 7 shows a schematic flowchart illustrating processing steps of the schedule display section 23 according to an embodiment of the present invention. By searching the schedule display table 31, step S162 obtains the first schedule display record "i" in the main schedule display area, which has a start position overlapping with the modified part. Next, step S163 judges whether it is in the horizontal mode. If the display is in vertical mode, the process goes to step S176 to execute steps S144-S152 shown in FIG. 6 . If the display is in horizontal mode, steps S164-S167 display the schedule data in the main schedule display area. First, step S164 judges whether or not the start position of the display record "i" overlaps with the modified portion. If the result is "Yes", the process goes to step S165 showing the i-th display recorded schedule event data. Next, the process goes to step S166 to set i=i+1. Thereafter, the process goes to step S167 to judge whether record "i" is the last displayed record before the right end point of the working time. If the result is "No", the process goes to step S164 to repeat the drawing process until the start position of the display record "i" overlaps with the modified portion, or after the right end point of the working time of the display record "i". By searching the schedule display table 31, step S169 obtains the first schedule display record "i" in the sub-schedule display area, which has a start position overlapping with the modified part. Next, step S170 judges that the start position of the display record "i" overlaps with the modified portion. If the result is "Yes", the process goes to step S171 to show the schedule event data of the display record in the sub-schedule display area. Next, the process goes to step S172 to set i=i+1. Thereafter, the process goes to step S177 to judge whether record "i" is the last displayed record before the left end point of the working time. If the result is "Yes", the process goes to step S174 to adjust the record to be the first schedule record after the left endpoint of the working hours. Next, step S175 judges whether the record "i" is the last display record. If the result is "No", steps S170-S175 are repeated until the start position of the display record "i" overlaps with the modified portion, or the display record "i" is the last display record.

In the following, the schedule display table according to the present invention will be described with an example. Figure 8 shows an example according to this application, wherein Mr. Ouyang's schedule on August 15, 1996 is displayed in vertical mode, without setting the left and right end time points of the working time, and the length L of the time axis is set to 1440 pixels, and the width of the schedule display area is set to 300 pixels. FIG. 9 shows a schedule display table and display data for one day according to FIG. 6 . Be set in the time period from 08:00AM to 17:00PM in working hours, by the program of the flow chart of schedule display list management part 30, step S79 judges whether the left and right endpoints of working hours change, as shown in Fig. 4 Show. Step S83 calculates the coordinates of the start point (left time point) of the working time as s=480, and calculates the coordinates of the end point of the working time (right time point) as e=1020. Step S84 calculates the calendar events before and after the new working time. In this case, both CLeft and CRight are 1. When the period of working hours is changed, the modified part in the display area is not deleted. Therefore, the schedule display table includes a main schedule display area, a secondary schedule display area and a time axis display area. Through the flowcharts shown in FIGS. 6 and 7, the time axis display area 22 and the schedule display area 23 modify the main schedule display area as shown in FIG. When the user selects the schedule events before and after the working time to display, through the flowchart shown in FIG. 7 , the sub-schedule display area is shown in FIG. 11 , and the main schedule display area remains unchanged. When the user changes the vertical mode to the horizontal mode, the schedule display list is displayed as shown in FIG. 12 through the flowchart shown in FIG. 7 . When the user selects to reduce the display screen, the schedule display list is displayed as shown in Figure 13, where the height value of the main schedule display area changes from 133 to 106 pixels, and the height value of the secondary schedule display area changes from 76 to 24 pixels. If the user scrolls up the sub-schedule display area, according to the flowchart shown in FIG. 5, step S131 obtains the first display record (i=0) of the sub-schedule display area. Since there are two display records in the sub-schedule display area, step S132 judges that the sub-schedule display area is scrolled up. By searching the schedule display table 31, step S137 sets the display height of the display record "i" to n=24. Correspondingly, the coordinate range of the modified part is represented by (0, y-n, x, y)=(0, 52, 300, 76), wherein the width of the sub-schedule display area is represented by x=300. In response to the modified portion, by the procedure in the flowchart shown in FIG. 7, steps S169 and S170 judge that no display record overlaps with the modified portion, and do not execute the drawing action. The result of scrolling up the secondary schedule display area is shown in FIG. 14 . When the user wants to scroll up the main schedule display area, through the procedure in the flowchart shown in FIG. 5 , step S121 obtains the first display record (i=0) of the main schedule display area. Step S122 determines executable scrolling. Steps S123 and S124 determine that the type of scrolling is horizontal upward. By searching the schedule display table, step S126 obtains the display height of record "i", which is represented by n=24. Step S127 performs scrolling in the vertical display mode, and step S128 obtains the modified part in the main schedule display area. The coordinate range of the modified part is represented by (0, y-n, x, y)=(0, 82, 300, 106). The result of scrolling up the main schedule display area is shown in FIG. 15 through the flowchart shown in FIG. 7 in response to the modified portion. If the user wants to delete the schedule event of 10:00-12:00 AM, by clicking the mouse pointer at the position of the desired schedule event, he can access the schedule editing device to perform deletion. The results are shown in FIG. 16 . After the desired schedule event is deleted, by the flow chart of the schedule display list management section 30, steps S71 and S72 shown in FIG. 4 judge that the edited type is schedule deletion in the vertical mode. Step S75 deletes the third schedule record in the main schedule display area. After deletion, step S101 detects that the type of editing is schedule deletion in horizontal mode, and the process goes to step S106. Since the schedule event to be deleted is the first schedule event on the display screen, step S106 calculates the display height of the target schedule event, which is represented by sy=0, and step S107 calculates the end position of the target schedule event in the display area The height of , which is represented by ey=106. At the same time, detection of modified parts needs to be performed in the time axis. Step S113 performs deletion similar to the vertical mode to detect the modified portion. In other words, similar to step S102, the start and end positions of the target schedule event in the time axis are calculated, where s=600 and e=720. Thereafter, step S114 calculates the coordinate range of the modified part of the main schedule display area, which is represented by (0, sy, x, ey)=(0, 0, 300, 106), and calculates the time axis (600, 0, 720 , y) the coordinate range of the modified part, where "y" is the display height of the time axis. In this preferred embodiment, the display height of the time axis is shown by 24 pixels, and the unit time period (60 minutes) is shown by 48 pixels. After calculation, the coordinate range of the modified part of time is (96, 0, 192, 24). With the flowchart shown in FIGS. 6 and 7 , the final result of the main schedule display area and time axis is shown in FIG. 17 .

As mentioned above, in the schedule display table, the start and end time points are recorded in the time axis and the altitude occupied by each schedule event in the schedule display area. With this schedule display table, the deleted portion of the modification area does not need to perform repeated calculations, and the modified portion in the time axis, the main schedule display area and the sub-schedule display area can be deleted in a faster and simpler manner. Therefore, the time axis display section can very quickly and easily draw the time axis with schedule time allocation according to the schedule display table. All schedule events for one day are displayed in the main schedule display area and the secondary schedule display area respectively. The distribution of calendar events can be distinguished by the start and end time points of working hours. The schedule event data can be managed in such a manner that each schedule event can be clearly and efficiently browsed and edited.
