Yes, the units displayed vertically will end with the value specified in 
upper limit. So if you use 10000000 as upper limit, you will get 10G as 
max value for the graph.

 From the rrdtool manual:

"Limits

[-u|--upper-limit value] [-l|--lower-limit value] [-r|--rigid]

By default the graph will be autoscaling so that it will adjust the 
y-axis to the range of the data. You can change this behavior by 
explicitly setting the limits. The displayed y-axis will then range at 
least from lower-limit to upper-limit. Autoscaling will still permit 
those boundaries to be stretched unless the rigid option is set."

Hi. Vincent.
Thanks for the great help and for the quick answer.

The answer maybe just what I need.
But I have another question to ask.
What is the meaning of "Limit"?
Does the "Limit" mean the maximum value for a network?
Say, a 10G network, if I set the template for "Upper Limit",
so I can get 10G graph.
Is that correct?

Appreciate for any information.

I'm not sure if I understand your question properly. If you wanna set a 
maximum value on the graph, you should tweak the graph template 
associated with the graph.

Unticking the "Auto Scale" option and setting the "Upper Limit" should 
give you what you want :-)

Hi.

We have a 10 Gigabit network. For the maximum value,
we need 2G (2000M) to display on the graph data.
Is there anyone know, it is possible? Or need more skill to customize?

Appreciate for any help or advice!

The issue I faced was with socket file. 
Fix1: configure mysql  
to have socket file as /var/run/mysql/mysqld.sock.
Fix2: Add following to php.ini:
mysql.default_socket=/path/to/mysql.sock 
- restart apache.
Here is my troubleshooting step: http://goo.gl/n5fEqh

Cheers.
