Hi,
I need to code histogram but I can not find a best way to do it. So, I'm expecting a histogram method. Is it possible to get this method into next release ?

Best regards,

Arthur

Anything is possible, but it's not something I'm working on right now so it's unlikely to be in the 0.9.9 release unless someone else writes the code.

You can plot histograms with JFreeChart now, but you have to do a bit of work to create the right dataset (some implementation of the IntervalXYDataset). When I do finally work on histograms, my efforts will go into some utility methods for creating such datasets automatically from sample data.

I just contributed some code that makes it pretty easy to create histogram data sets, and a factory method that creates a VerticalXYBarChart that makes sense for a histogram (replaces the date axis with a number axis).

It's a sourceforge RFE, just check the site.

Thanks for the code...I've incorporated it for the 0.9.9 release.
