Hi,
rendering some of my charts takes almost 50GB of RAM. I believe below is a
stracktrace
of one such situation when it already took 15GB. Would somebody comments on
what is
matplotlib doing at the very moment? Why the recursion?
The charts had to have 262422 data points in a 2D scatter plot, each point
has assigned
its own color. They are in batches so that there are 153 distinct colors but
nevertheless,
I assigned to each data point a color value. There are 153 legend items also
(one color
won't be used).

Clues what is the code doing? I use mpl-1.3.0.
