Achartengine display values inside the series areas and horizontal legend

I have tried the following with the default renderer

CategorySeries series = new CategorySeries("First test");
int numSlide = portions.length;
for (int i = 0; i < numSlide; i++){
    series.add(seriesNames[i]+" ("+portions[i]+" %)", portions[i]);
}
DefaultRenderer defaultRenderer = new DefaultRenderer();
SimpleSeriesRenderer simpleSeriesRenderer = null;

for (int i = 0; i < numSlide; i++){
    simpleSeriesRenderer = new SimpleSeriesRenderer();
    simpleSeriesRenderer.setColor(colors[i]);
    simpleSeriesRenderer.setChartValuesFormat(new DecimalFormat("###,###,##0.0"));
    defaultRenderer.addSeriesRenderer(simpleSeriesRenderer);
}

defaultRenderer.setInScroll(true);
defaultRenderer.setZoomButtonsVisible(false);
defaultRenderer.setZoomEnabled(true);
defaultRenderer.setLabelsTextSize(18); //value size
defaultRenderer.setLabelsColor(R.color.primary_dark);
defaultRenderer.setShowLegend(false);
defaultRenderer.setClickEnabled(true);
defaultRenderer.setPanEnabled(true);
defaultRenderer.setShowLabels(true);
defaultRenderer.setShowLegend(true);

//return the pie chart view
return ChartFactory.getPieChartView(context, series, defaultRenderer);

Now the above produces

What am looking forward to get is to have the percentage values eg: 2% inside the chart area something which looks like this

How do i get the percentage values to be displayed inside the charts?

Solution

  • You want to display values and hide labels. Do that like so in your renderer:

    defaultRenderer.setShowLabels(false);
defaultRenderer.setDisplayValues(true);

    Also, your series names should probably not contain the values, so change the following line

    series.add(seriesNames[i]+" ("+portions[i]+" %)", portions[i]);

    to

    series.add(seriesNames[i], portions[i]);
