Current cell's graphic context will cover only the region within the cell, therefor even if you try to render larger drawings, the portion with in the region alone will be visible.
#1. Try extending the region of the the current graphic context, before painting anything and reset it after the paint is done.

#2. Try painting from the parent controls context.
The later option would be neat and appropriate.
Hope this helps!!!
