Mpandroidchart: java.lang.ArrayIndexOutOfBoundsException

[Vojtas87]

Hello,

I use your library for my app. Thank you very much for your work, it looks perfect. My users reported some problems, so could you please take a look, if there is some bug in your code or am I doing something wrong? Thank you for your response.

Android 4.4, Samsung Galaxy S4 Mini

There is code in my app:

`public class MyXAxisValueFormatter implements IAxisValueFormatter {

    private String[] mValues;

    public MyXAxisValueFormatter(String[] values) {
        this.mValues = values;
    }

    @Override
    public String getFormattedValue(float value, AxisBase axis) {
        // "value" represents the position of the label on the axis (x or y)
        return mValues[(int) value]; // line 461
    }

}`

LineData data = new LineData(dataSets); holder.lineChart.setData(data); XAxis xAxis = holder.lineChart.getXAxis(); xAxis.setValueFormatter(new MyXAxisValueFormatter(values)); xAxis.setGranularity(1f); xAxis.setPosition(XAxis.XAxisPosition.BOTTOM); xAxis.setTextSize(11f); xAxis.setTextColor(getResources().getColor(R.color.TextColor)); xAxis.setDrawAxisLine(false); xAxis.setDrawGridLines(true); xAxis.setGridColor(getResources().getColor(R.color.grey300));

And there is something similar, maybe, Android 5.1, Moto G:

[erwin009]

me too, same problem

[anyeloamt]

I had this issue too, I resolved with something like this.

@Override
    public String getFormattedValue(float value, AxisBase axis) {
       int intValue = (int) value;

       if (mValues.length > intValue && intValue >= 0) return mValues[intValue];

        return "";
    }

[GuoZhaoHui628]

me too,why?
sometime times is ok,but is not work mostly ,and I don't change the code

[mdomanski92]

Try this:

axis.setGranularity(1f);
        axis.setValueFormatter(new IAxisValueFormatter() {
            @Override
            public String getFormattedValue(float value, AxisBase axis) {
                String val = null;
                try {
                    val = labels.get((int) value);
                } catch (IndexOutOfBoundsException e) {
                    axis.setGranularityEnabled(false);
                }
                return val;
            }
        });
