Histogram.

[Shirley]

Hi,
I need to process a vector of raw data into histogram.
I think I should use createVerticalXYBarChart, but not sure. Am I right?

Another question is there some third part package process the data into histogram data? I am lazy.
Thanks for your help!

I think the vertical XY bar chart would work well for histograms...what is needed is some code to create the required IntervalXYDataset.

I've created a custom data type for Histogram data, and if you want it, I'd be happy to send it to you. I've created some pretty nifty plots using your program, and it is very impressive.

Hi Ray,

I'm interested in looking at your code, as I'm sure others are too. One way to make it available would be to raise a 'Histogram dataset' feature request on the JFreeChart project page at SourceForge, and then attach your code to the request. Or you can just e-mail it to me if you prefer...
