Description yeray alonso 2017-01-02 08:20:16 EST 
The attached application has a toolbar/actionBar and uses appcompat to support older android APIs.

If you create several charts in a ScrollView and you scroll it, the charts are drawn over the actionBar.

Problem reproduced with x86 emulators from API 15 to 23.
Works fine with x86 emulator API 24.
Works fine with ARM emulator API 10.

The legend visibility affects the behaviour; if you hide it, the problem doesn't appear in those emulators where it did.

A workaround is to disable the Hardware Acceleration. Ie:

        if (Build.VERSION.SdkInt > BuildVersionCodes.GingerbreadMr1)
          chart.SetLayerType(LayerType.Software, null);
