Currently ShinobiCharts for Android does not directly support clipping options for Annotations. It should be possible to achieve this, but we will need to do a little more work
Firstly, you would need to implement the following listener interface:
Once informed that the chart has been laid out, you would need to use the data values of where you wish to place the non-clipped annotation, and covert them to pixel values. The pixel values you need are those which are relative to the chart, rather than the plot area. The axis class offers just such a method:
This method will give you the appropriate pixel values which as I say are relative to the chart. With this information you should be able to add your own Android view, in place of the ShinobiChart annotation. You will also of course be at liberty to place it in front or behind the chart plot area.
I hope that you find this information useful.
Thanks and kind regards,
