MPAndroidChart RadarChart minimizes itself

Question

I have some problems with RadarChart tags. In particular, if I use long texts (for example, 15-20 characters), and the available space is not too large, the chart crashes and the labels are placed inside the collapsed chart (but there is clearly more free space).

I tried to use a ValueFormatter for the label axis, which truncates the labels if they are longer than 5 characters, but as I can see, the calculation of the size of the chart is based on the full text of the label, since the chart crashed the same way I described it before.

 XAxis xAxis = radarChart.getXAxis(); xAxis.setValueFormatter(new XAxisValueFormatter() { @Override public String getXValue(String original, int index, ViewPortHandler viewPortHandler) { return original.length() > 5 ? original.substring(0, 5) + "…" : original; } }); 

Here are some photos to clarify the problem. Charts are displayed inside CardView , and, as you can see, there is a lot of free space on all sides. The first two pictures are taken with the ValueFormatter set, the last two without it.

You probably have some errors, here are some solutions:

1) Set your radar data after you set the RadarChart parameters, then call invalidate() ;

2) Set AxisMinimum and AxisMaximum to radarChart.getXAxis() and radarChart.getYAxis()

3) Call yAxis.calculate(min,max) after step 2;

4) If necessary, use radarChart.setExtraOffsets(?,?,?,?)
