Hi Torquil,
thanks again for this report. I made changes to wxwidgets driver which
should at least partially resolve your problems.

If you don't set the smooth option to 0 (it's set to 1 by default),
the font will be plotted antialized. This looks rather pretty, but is
very slow compared to the non-antialized case. So in your case, set
smooth always to 0. You should also be able to improve the plotting
speed a little bit, by setting the antialized option to 0 (it's also
set to 1 by default) - here the lines, etc. are plotted antialized,
looks very nice, but has small impact on the speed (about 10-20%).
Only in case your plplot version supports this option.

There is no db option in the wxwidgets driver, since it's used by
default. In order to improve the time needed for a plot, the wxWidgets
driver plots into a memory canvas and only updates the window after
about 5000 commands (lines, fills, etc.). It also doesn't copy the
whole window, only parts of it, which changed. The reason why you
didn't see much when using pgclear() was, that I didn't update the
window before I cleared it :) Therefore much of what was plotted never
made it to the screen :).
Anyway, I commited the change to the svn repository and if you compile
plplot from the repository, there should be now no flickering and nice
animation of your plot.

Sure. But shouldn't be much slower if you use the smooth=0 option.

I can see that too, but I have still to investigate why this happens.
