Description

For example if you wish to display the percentage in the label it's currently not possible.

My proposal is to add a new parameter named "pie_label_format" for that.

When this issue is fixed you'll be able to use:

{{chart type="pie" source="xdom" params="document:ActiveInstalls.VersionsData;range:B2-B.;series:columns;pie_label_format:{0} - {2}"/}}

See http://www.jfree.org/jfreechart/api/gjdoc/org/jfree/chart/labels/StandardPieSectionLabelGenerator.html to understand the format.

Technically this calls the following jfreechart API:

        // Allow customizing the label to use
        String pieLabelFormat = parameters.get(PIE_LABEL_FORMAT_KEY);
        if (pieLabelFormat != null) {
            piePlot.setLabelGenerator(
                new StandardPieSectionLabelGenerator(pieLabelFormat, NumberFormat.getNumberInstance(),
                    NumberFormat.getPercentInstance()));
        }
