Drawing and Writing Graphs to File

[tlohan]

Hi,

I'm new to Java.
I have a file that contains performance stats of type:

Time IO CPU ............
10:20:00 100.25 8.93 ............
10:25:00 150.89 14.61 ............

I want to be able to create graphs to map such things as IO over Time or CPU usage over Time and then to input these graphs into a Report File.

Can anyone point me to a link where I may be able to learn how to do this. Or could you give me some pointers to get me started.

Any help is greatly appreciated.

Thanks,

Tom
