mean, stdev, range, quartile plot

Is there a chart and an analysis package in JFreeChart for displaying basic statistical information about series data? For example, I have several groups of data (sorted by series) and I want sumarize their means, stdev, range, and quartiles (like JMP or RS1 or SAS would produce) for quick comparison? It would probably look something like a merger of the XY Bar Chart and the high-low-open-close chart or a merger of the stacked bar chart and the xy line chart.

Is there an existing package? One under development? Has anyone else requested these too?

Just thought I'd ask! Thanks!

Gary

Two demos to look at are BoxAndWhiskerDemo.java and XYBoxAndWhiskerDemo.java. They are the closest there is to what you are asking for, so they would be a good starting point.

Thanks Dave!

I found the Boxandwhiskerdemo and was able to compile it. However, I can't get the demo to run. I'm getting an exception:

Exception in thread "main" java.lang.NoClassDefFoundError: BoxAndWhiskerDemo (wrong name: org/jfree/chart/demo/BoxAndWhiskerDemo)

Also, I can't get jfreechart-0.9.16-premium-demos.jar to run either. Normally, I just double click on a jar file and it runs. I don't get any error messages.

Thanks!

Gary

I got boxandwhiskerdemo running - removed the 'package' statement.
