The matplotlib setup.py file looks for both Numeric and Numarray and
sets the build configuration to 'both', if you have them. This is your
situation, so you should have access to both of them. If it is not
finding Numarray, then you'll have to modify your PYTHONPATH variable
to point to the numarray library. Also make sure you have the numarray
include files.<br>
<br>
To use numarray, set the numerix keyword to numarray in your
.matplotlibrc file.<br>

Hello,
in case someone has the same problem as me -- to display accented
letters in matplotlib -- this is how to do it:
#! /usr/bin/python
# -*- coding: iso-8859-2; -*-
import matplotlib
matplotlib.use('GTK')
from pylab import *
plot([1,2,3])
title(u'some accented letters: =C4=9B=C5=A1=C4=8D=C5=99=C5=BE=C3=BD=C3=A1=
=C3=A1=C3=AD=C3=A9')
#savefig("pokus.eps")
show()
Important is "use('GTK')" (Agg backend only shows rectangles instead of
accented letters) and "title(u'some..." (the "u" -- without it it
doesn't work either).
You can save the figure to *.png, unfortunately saving to *.eps or *.ps
doesn't work (even using different backend).

Hi, I have a long annoying problem: how can I make the installer compile for numarray instead of Numeric? For compatibility reason I have both on my machine and prefer numarray (and an installer:-)). It seems the installer detects the presence of Numeric prior to numarray. Is there any configuration available? Thanks. =20 Cheers, Yang =20
John,
Below is a version of the script that works. The problem is windows does
not put out binary. The example in the matplotlib documentation should
be updated to point out this machine compatibility issue unless someone
knows a better way.
#!d:/apps/Python23/python
import os, sys, msvcrt
from pylab import *
plot([1,2,3,4])
print "Content-type: image/png\n"
msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)
savefig(sys.stdout)
Best wishes, Simon
