How do I add a unit to the value labels in MPAndroidChart?

Question

I want to attach a unit to the value labels. How do I do that?

Answer 1

You can do this by writing an implementation of IValueFormatter as in the answers to this question :

public class MyValueFormatter implements IValueFormatter {

    private DecimalFormat mFormat;

    public MyValueFormatter() {
        mFormat = new DecimalFormat("###,###,##0.0");
    }

    @Override
    public String getFormattedValue(float value, Entry entry, int dataSetIndex, ViewPortHandler viewPortHandler) {
        return mFormat.format(value) + " km";
    }
}
