Re-Generate legend, through apply_callback/Apply

anykraus · anykraus · commit 0bc4c523c0fb · 2014-04-02T15:03:21.000+02:00
If there is a legend, it is re-generated when "Apply" is clicked. See Issue #2934: Might have side effects. #2934 tacaswell: "However this will clobber any legend that is not the auto-magically generated one so it should probably also get a tick box to enable/disable the updating of the legend." Tick box not included.
