XAxisRenderer.drawLabels() - java.lang.ArrayIndexOutOfBoundsException #2321

Open oxoocoffee opened 8 years ago

I am on beta1 tag and found this reproducible issue where

mXAxis.mCenteredEntries is empty causing blow out. I am basing my code from your sample. DynamicalAddingActivity.java

positions[i] = mXAxis.mCenteredEntries[i / 2]; <------

In my case I do not add any data after starting my app so chart is empty. Then I try to pinch with my fingers on empty chart (Found this by accident :)

Here is full stack
