Details:
When a fresh figure is created via "plot", Qt graphics toolkit will first draw
an empty axes before doing the actual plot. This creates a sort of flashing
effect sometimes.
Launch Octave GUI and create a slow plot with many points such as:
plot(1:1000000)
Notice how there are empty axes with extent (0:1) x (0:1) while the large draw
is waiting to complete. This does not happen in FLTK graphics toolkit.
If the figure is first created, neither does the empty axes appear. Try
figure
plot(1:1000000)
With "figure" there is a new window, but completely blank. With the "plot"
the window remains blank until the (0:1000000) x (0:1000000) axes appear.
