Importing Matplotlib is very slow for me, too. For a wxPython application
with embedded Matplotlib, I am getting "load" times of > 20 seconds when
"cold" importing matplotlib, with this (circa mid 2004) computer setup:
Windows XP, sp3, Intel Pentium, 1.70 Ghz, 1 GB RAM.
This is, by the way, an import well after Python and wxPython have already
been loaded into RAM, as it happens by a user action, so none of the time
involved here is due to loading Python or wxPython (they both load more
quickly--about 10 seconds to cold import them, my code, images, and some
other libraries).
First of all: does that amount of time seem appropriate for that fast of a
system--or is that too long? It definitely *feels* way too long from a
user perspective (for comparison Word or PowerPoint loads on this computer
in about 2.5 seconds).
Trying to improve it and following this old thread, I have switched to
matplotlib.use('Agg')
instead of
matplotlib.use('wxAgg')
as suggested to speed things up...but it is no faster.
I see, though, that I also have lines such as:
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg
from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg
Would the presence of these imports obviate the fact that I switched to
using the Agg instead of the wxAgg? If so, is there any way to use
something faster here (I suspect not but thought I'd ask).
Also, what else should I consider doing to reduce the import time
significantly? (I have to learn how to use the profiler, so I haven't done
that yet).
Thanks,

The color part of this issue is known, and was fixed for v1.1.1, I
believe. Certainly for v1.2.0. Please double-check your matplotlib
version. As for the alpha issue, that is a tough one that I am working on
in a personal branch. The issue is that mplot3d uses transparency as a way
to simulate "depth". Scatter markers further away are "foggier", kind of.
This means that any alpha provided by the user is immediately over-written
upon display.

I was stumped by trying to install basemap because I took the easy way out with the Geos dependency and installed the latter via mac port; this, however, does not give you the include directory.
I get the includes from installing geos via MacPorts:
