histograms

[matt]

hi,
I'd like to use JFreeChart to display histograms. Histograms differ from vertical bar charts in 3 simple ways:
1. bars are the same color
2. no gap between bars
3. horizontal axis is a value axis, not a category axis.

1 is straightforward, but it seems that to accomplish 2 and 3 I need to write a new histogram class that's a cross between verticalBarPlot and XYPlot that draws bars on two value axes.

Has anybody done this before, or is anybody working on this?
Thanks,
matt

Hi Matt,

The VerticalXYBarPlot class draws a bar plot using a numerical x-axis. I think you should be able to use this for histograms. It uses the IntervalXYDataset interface for data...
