Grouping minor/insignificant values of a Pie Chart

Hi,

Has jfree chart implemented a heuristic that will group segments of a
pie chart that are too small or insignificant to dedicate an entire segment and
label for?

For example, say I have a dataset of 100 values to draw, I would only like to show the top 10 values separately. The others would be grouped together in a single segment titled 'other'. Is there a means to do this?

Cheers,
Nick

The DatasetUtilities class has a createConsolidatedPieDataset() method that does something along these lines. You need to apply it to the original dataset - it will return a new dataset that you add to the plot.

Possibly the PiePlot class could be extended to support this more directly.
