android – MPAndroidChart: Hide 0 value labels in a stacked bar chart

Posted by: admin June 15, 2020 Leave a comment

Questions:

I am using MPAndroidChart to show a stacked bar chart containing two sets of data (Income and Expenditure). I’m having an issue when the value is 0 the label overlap other x axis values.

In the case of the screenshot you can see that the bars which have values have overlapping values for the following dates: 14/4, 15/4 and 16/4.

How can I hide the 0 values to stop the overlapping issue?Stacked bar chart graph

How to&Answers:

Use the IValueFormatter interface.

Example:

public class MyValueFormatter implements IValueFormatter {

    private DecimalFormat mFormat;

    public MyValueFormatter() {
        mFormat = new DecimalFormat("

Answer:

,

Answer:

,##0.00"); } @Override public String getFormattedValue(float value, Entry entry, int dataSetIndex, ViewPortHandler viewPortHandler) { if(value > 0) { return mFormat.format(value); } else { return ""; } } }

Set it for the chart-data:

barData.setValueFormatter(new MyValueFormatter());
