Update of bug #47216 (project octave):

                  Status:                   Fixed => In Progress            
             Open/Closed:                  Closed => Open

Follow-up Comment #4:

Alas, I'm re-opening this bug report.  The problem is that certain plots have
become unbelievably slow.  So slow, that I can see the updates.

The set of legend demos 30-34 are good ones to test with.


demo legend 30


I thought it was related to callbacks, so I undid the fix for this bug report,



hg backout -r 4f0f9f029d12
make
run-octave
demo legend 30


and now it works.

I think the solution is to be smarter about what updates we do.  If there are
loads of callbacks executing which are not related to a ui* object it is
probably because we are constructing a complicated graphics object.  We should
just wait until we hit the command line again to display the final graphic. 
But for objects which will never hit the command line, like a uicontrol, we do
need to update the plot.
