Androidplot: Decimal Places in Point Label

Question

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));

could you be more specific – Pragnesh Ghoda シ May 31 '14 at 08:06 — Pragnesh Ghoda シ, May 31 '14 at 08:06

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.

The answer provided by Nick is for old version. The PointLabeler method has been moved into LineAndPointFormatter. The latest working example has been provided by Nick in another thread: https://stackoverflow.com/a/39482297/9969285

PointLabelFormatter() and the other *Formatter() APIs don't offer a way to choose your decimal format. My guess is that you need to format your series data prior to calling plot.addSeries().

Yeah I guessed the same too. I hope someone more knowledgeable in Androidplot can confirm this. – davidleejy May 31 '14 at 08:12
