[Octave-bug-tracker] [bug #40663] statter and scatter3 terribly slow

[Rik]

Follow-up Comment #2, bug #40663 (project octave):

We do need a test case.  But first, some observations.  The gnuplot backend
will always be slower because the communication is done over pipes, choose
fltk for speed.  Second, the scatter routines were overhauled in the current
development branch and 3.6.4 is not worth comparing for speed.  Third, there
are breakpoints in the code.  Below 100 points a different algorithm is used
so it is important to know which regime you are finding slow.  Fourth, scatter
relies internally on the patch function which has yet to be overhauled for
speed.  Improving patch() may solve most of the problems.
