Hi,
To improve plotting speed, I decided
to use blitting(canvas.copy_from_bbox(), canvas.restore_region() &
canvas.blit()) instead of canvas.draw(), however panning & zooming stops
working after this change. Now, when I click on the 'Pan/Zoom' button or
the 'Zoom to rectangle' button on the Navigation Toolbar, my plot becomes
empty. I don't know what's going wrong, can someone please point me in the
right direction?
Thank you,
Clare.
