[Octave-bug-tracker] [bug #56645] animatedline()

[William H. Hooper]

Follow-up Comment #2, bug #56645 (project octave):

The good news: bounce(), animatedline(), and demo_animatedline() all compiled
and ran under octave, both from the command line and within the octave-gui
application.  I just just needed a graphics toolkit to support them; I
installed gnuplot-qt via homebrew.  Thanks, arb!

The bad news: the graphics window flickers with each movement.  The flickering
is bearable when octave-gui runs bounce.m, but not when it runs 
demo_animatedline.  None of the animations run well from the command line; the
drawing window opens properly, but the refresh flicker ruins the effect of
animation.

More bad news: the graphics routines consume inordinate resources.  Running
the original bounce.m (which contained an infinite loop) from the command line
locked my machine; each refresh brought the drawing window into focus, so I
couldn't even keep a Terminal window in front long enough to type a kill
command.  Even within octave-gui, the graphics routines cause the fan to spin
up, unlike their counterparts in Matlab.

I suspect that many of these problems come from gnuplot-qt.  If I'm able to
import a graphics toolkit that works better, I'll post an update.
