Abstract

PURPOSE:To generate a necessary graph by editing a basic graph pattern graphic-displayed in display in accordance with the numerical change of respective graph items. CONSTITUTION:At first, a basic graph generating means 1 generates the designated basic graph pattern and a graph displaying means 2 displays the basic graph pattern. After that, a graph editing means 3 executes an editing operation such as the expanding and reducing, etc., of the respective areas in the basic graph pattern displayed in display so that the graphic-displayed basic graph pattern is changed into the necessary graph.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for creating graphs for displaying graphics on a display.

0002

[Prior Art] In the graph creation function of conventional word processors, a table in which items, numerical values, etc. are input is created in advance, and the number of items in this table, item names, graph creation area, graph type, etc. are used as parameters. If specified, a graph will be created in the specified creation area. (a) of FIG. 4 is
2 is a flowchart showing a procedure for creating a graph using a conventional personal word processor. FIG. 4B is an exemplary diagram of a table necessary to create a graph. FIG. 4C is a diagram illustrating the graph data designation area 12 necessary for creating a graph. FIG. 5 is an exemplary diagram of a pie chart created based on the table shown in FIG. 4(b).

Next, the operation will be explained. First, in step 7A, a table for inputting numerical data shown in FIG. 4(b) is created, and numerical values are input for each item in this table. Next, in step 7B, the graph data specification area 12 necessary for graph creation in FIG. 4(b) is specified. An example of specifying the graph data is shown in FIG. 4(c). After specifying on the display screen the area in which the graph will be created in step 7C, the type of graph (pie graph) is specified in step 7D, and the pie chart is created in the creation area specified in the above procedure in step 7E. When created, each of the divided regions 4, 8, 10, and 11 within the circle is divided at a ratio according to the numerical data of each item.

0004

The graph creation function of conventional word processors has had the problem of having to create a table for specifying parameters even when only a graph is required.

[0005] This invention was made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a graph creation method that can obtain the necessary graph without creating a table when only a graph is required. It is an object.

[0006]

[Means for Solving the Problems] A graph creation method according to the present invention includes a basic graph generation means for generating a basic pattern of a specified type of graph, and a graph display means for displaying the basic graph pattern. , graph editing means is provided for changing and displaying corresponding numerical values and items as each area of the displayed graph pattern is enlarged, reduced, changed, and items changed.

[0007]

[Operation] In this invention, the basic graph generation means generates a basic graph pattern, and the graph editing means performs editing operations such as changing the graph, changing elements, enlarging, and reducing the basic graph pattern into a necessary graph. Change to

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1(a) is a block diagram according to an embodiment of the present invention. In the figure, 1 is a basic graph generation means for generating the basic graph pattern of the required graph, 2 is a graph display means for displaying the generated basic graph pattern, and 3 is for changing the number of items and elements for the displayed graph. This is a graph editing means for performing editing operations such as changing, enlarging, reducing, etc.

Next, the operation of the above embodiment will be explained with reference to FIGS. 1 to 3. FIG. 1(b) is a flowchart showing the operation of this embodiment, FIG. 2(a) is an illustration of the basic pattern of a pie chart, and FIG. 2(b) is a pie chart required by the operator in this explanation. It is. Figure 3 (a), (b)
) is a diagram showing changes in the display screen when editing a pie chart.

For example, when the operator creates a pie chart with four items, first, in step 2A of FIG. 1(b), the basic graph generating means 1 generates the items shown in FIG. 2(a). Generate the basic pie chart pattern of number 4. After the generation, in step 2B, the generated basic graph pattern is displayed by the graph display means 2. Next, in step 2C, the displayed graph is edited by the graph editing means 3 to create a necessary graph. As an example of graph editing, area 4 of item A in Fig. 3(a)
We will explain the case of expanding. In order to expand the area of item A4 displayed in outline in FIG. 3(a), the boundary line 6 between item A4 and item B8 is selected with the cursor 9. Then, as shown in FIG. 3(b), the cursor 9 is moved down to the desired area to be expanded. At this time, the boundary line 6 is also moved in accordance with the movement of the cursor 9. Numerical value 5 indicates the proportion of the area of item A4, which changes and is displayed in real time according to the changing area of item A4 by the above operation. Furthermore, when changing the legend name A7 corresponding to item A4, select the legend name A7 with the cursor 9 and input the required legend name. By performing similar operations on item B8, item C10, and item D11, the necessary graph shown in FIG. 4 can be created.

Although this embodiment describes the creation of a pie chart, it is also possible to create other graphs such as bar graphs, line graphs, band graphs, radar charts, etc. using the same operating method. Further, in this embodiment, a word processor has been described, but it may also be implemented as software for an electronic computer such as a personal computer. Furthermore, in addition to displaying the basic graph pattern, it is also possible to simultaneously display the minimum basic items required for graph display to notify the operator.

[Effects of the Invention] According to the present invention, after selecting a suitable pattern from basic graph patterns and displaying it on the display, the number of items, elements, enlargement, reduction, etc. can be performed on this basic graph pattern. The necessary graph can be created by editing or rewriting the item name and legend name, so you can easily create a graph without creating a table to specify parameters. becomes possible.
