Hi,
Thanks for bringing the issue of HidePartialLabel does not hides the last label into our attention. I have logged a bug report on this issue and will update you as soon as the bug is fixed.
As an workaround, you can raise the ChartFormatAxisLabel event which allows you to modify/delete the labels from the collection.
Please refer the attached sample which deletes the last label using the ChartFormatAxislabel event.

Kindly let me know if this helps you.
Thanks and Regards,
Geetha.
