Creating 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

You'll need to construct the graph as a GUI component (a swing container of some sort) and then print that.

JClass is a package that will create graphs, but it's a little pricey...

Does anyone know of a cheaper one?

I'd write the data out to an excel file. It's easy using the JDCB-ODBC bridge driver. Then it's super easy to convert that data to a graph.

look at this:

Hope that helps somewhat
