[SOLVED] Androidplot: Decimal Places in Point Label

Androidplot: Decimal Places in Point Label

I would like to be able to set the number of decimal places for point labels. Currently, my point labels are overlapping one another like so:

Current label implementation is trivial:

myXYPlot.setPointLabelFormatter(new PointLabelFormatter(Color.BLACK));

Solution

You can implement the PointLabeler interface to get the behavior you're after; you need to set the PointLabeler for each series that should use the custom formatting. For example:

series1.setPointLabeler(new PointLabeler() {
    DecimalFormat df = new DecimalFormat("###.###");

    @Override
    public String getLabel(XYSeries series, int index) {
        return df.format(series.getY(index));
    }
});

It's a little less intuitive than applying formatting to domain and range labels but was necessary in order to allow each series to have its own point labeling scheme.
