Hi,

I am having problems getting charts to retain their state after a rotation.  For example, if I zoom in on a chart, or turn off some of the legend items, and then rotate the device (forcing the view to be recreated) the chart is no longer zoomed and has all of its legend items on again.  I know that OnSaveInstanceState and OnRestoreInstanceState are being called for the chart, so it is generating a Parcelable, but it doesn't seem that the saved state of the chart includes zooming and legend state.  Is this the expected behavior or a bug?

Thanks
