How to set X axis labels in MP Android Chart (Bar Graph)?

For the com.github.PhilJay:MPAndroidChart:v3.0.3

I am using a label list:

final List list_x_axis_name = new ArrayList<>();
list_x_axis_name.add("label1");
list_x_axis_name.add("label2");
list_x_axis_name.add("label3");
list_x_axis_name.add("label4");
list_x_axis_name.add("label5");

and setting the label like this:

BarChart chartBar = (BarChart) findViewById(R.id.chartBar);
XAxis xAxis = chartBar.getXAxis();
xAxis.setGranularity(1f);
xAxis.setCenterAxisLabels(true);
xAxis.setLabelRotationAngle(-90);
xAxis.setValueFormatter(new IAxisValueFormatter() {
 @override
 public String getFormattedValue(float value, AxisBase axis) {
  if (value >= 0) {
   if (value <= list_x_axis_name.size() - 1) {
    return list_x_axis_name.get((int) value);
   }
   return "";
  }
  return "";
 }
});

You just make a simple list of string like this :

final ArrayList<String> xAxisLabel = new ArrayList<>();
    xAxisLabel.add("Mon");
    xAxisLabel.add("Tue");
    xAxisLabel.add("Wed");
    xAxisLabel.add("Thu");
    xAxisLabel.add("Fri");
    xAxisLabel.add("Sat");
    xAxisLabel.add("Sun");

Then you do this :

    XAxis xAxis = chart.getXAxis();
    xAxis.setValueFormatter(new ValueFormatter() {
        @Override
        public String getFormattedValue(float value, AxisBase axis) {
            return xAxisLabel.get((int) value);

        }
    });

Hope this helps.

Kotlin:

val xAxisLabels = listOf("1", "2", "3", "4", "5", "6" ...)      
barChartView.xAxis.valueFormatter = IndexAxisValueFormatter(xAxisLabels)

Java:

ArrayList<String> xAxisLables = new ArrayList();
xAxisLables.add("1");
xAxisLables.add("2");
xAxisLables.add("3");
xAxisLables.add("4"); ...

OR

String[] xAxisLables = new String[]{"1","2", "3", "4" ...};

barChartView.getXAxis().setValueFormatter(new IndexAxisValueFormatter(xAxisLables));

You can prepare any data you want in xAxisLabels to display
