I'm seeing the same crash from from my app.  I can't repro myself (the crash was from my users).

Hi Mike,

We have never been able to reproduce this scenario. Theoretically it should be impossible and we have never experienced it even in the many test case that we have for the chart. If we manage to reproduce it somehow we will surely think of a way to fix/work around it.

If you have any more info about this we'd be grateful.

I wonder if this is caused by setData being called while something else is going on, like pinch-zoom/panning?  In my app I allow the user to filter on different ranges on the chart and it is also pinch-zoom/trackball enabled.  I am not able to repro myself, but seeing more reports of this in production.

Here's more info on where I'm seeing the crashes:

Device:
GT-N7100 - 2
SM-N900V - 2

OS:
4.3 - 2
4.4.2 - 2

Country:
GR - 2
US - 2

Hi Mike,

We will try to figure out how to avoid this, however if we can't find a reproducible case it would be difficult.
