Setting up maximum range for X and Y axis in CeWolf Chart

Hi all,

i am facing a problem with CeWolf Chart generation. I would like to set up the highest range for X and Y axis. But i am unable to get the expected result.

For example i have set up 600 as the highest range, but when the chart is rendered, only default range which is set by the library rendered automatically.

Please some one help me to solve this problem...

Thanks in advance.

My Chart Rendrer Page

index.jsp:

I don't see setMinVal and setMaxVal methods in the DatasetProducer class that would accept -and subsequently make use of- those values.

But regardless, cewolf always scales the axes to accommodate the actual values; there is no way to display larger axis value without larger actual data values. I'm not even sure if the JFreeChart library (which is used by cewolf) supports that.

As an aside, you should use the cewolf distribution downloadable from the link in my signature, not the one from SourceForge.
