Works fine here, thanks. It would be nice, though, if the plot
were to display somehow instead of just being written to file
in the background.
Ok, try this instead, I hope it should work on most python distributions
(not all backends are necessarily available even when python+numpy+mpl
are installed).
Actually, I'm not a matplotlib expert, and the reason is basically...
gretl! There was a time when some graph manipulations were difficult or
impossible in gretl (low-level gnuplot hacking aside), and I started
learning mpl. But you listened to users' demands and made some crucial
things possible and/or easy to do, and that's why I haven't used mpl a
lot. But relax -- you don't have to implement stacked area charts now in
gretl :-)
cheers,
sven
