Description Tilo 2015-08-04 09:04:16 EDT 
Hi, 

on our application we create a Chart with a bar series as follow:

private void createBarChart(int leakState)
{
  this.chart = new TChart(this.getContext());
  this.exampleBar = new Bar();

  //TODO Test Ende
  this.exampleBar.clear();
  this.exampleBar.add(new int[]{40, 20, 49, 60});
  this.chart.addSeries(this.exampleBar);
  //TODO Test
  this.chart.getZoom().setZoomStyle(Zoom.ZoomStyle.INCHART);

  LinearLayout chartLayout = (LinearLayout) this.findViewByID(R.id.layout_logger_detail_chart);
  chartLayout.addView(this.chart);
  chartLayout.setMinimumWidth(800);
}

If we zoom on the chart, the activity crashes, but only on Android 5.0 up to 5.1. If we do the same on Android 4.4.4 everything works fine.

Try disabling Hardware Acceleration in those platforms where it crashes. Ie:

  if (Build.VERSION.SDK_INT>10)
    tChart1.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
