+How do I use matplotlib in a web application server?
+====================================================
+
+Many users report initial problems trying to use maptlotlib in web
+application servers, because by default matplotlib ships configured to
+work with a graphical user interface which may require an X11
+connection. Since many barebones application servers do not have X11
+enabled, you may get errors if you don't configure matplotlib for use
+in these environments. Most importantly, you need to decide what
+kinds of images you want to generate (PNG, PDF, SVG) and configure the
+appropriate default backend. For 99% of users, this will be the Agg
+backend, which uses the C++ `antigrain <http://antigrain.com`_
+rendering engine to make nice PNGs. The Agg backend is also
+configured to recognize requests to generate other output formats
+(PDF, PS, EPS, SVG). The easiest way to configure matplotlib to use
+Agg is to call::
+
+ # do this before importing pylab or pyplot
+ import matplotlib
+ matplotlib.use('Agg')
+ import matplotlib.pyplot as plt
+
+Alternatively, you can avoid pylab/pyplot altogeher, which will give
+you a little more control, by calling the API directly as shown in
+`agg_oo.py <http://matplotlib.sf.net/examples/api/agg_oo.py`_ .
+
+You can either generate hardcopy on the filesystem by calling savefig::
+
+ # do this before importing pylab or pyplot
+ import matplotlib
+ matplotlib.use('Agg')
+ import matplotlib.pyplot as plt
+ fig = plt.figure()
+ ax = fig.add_subplot(111)
+ ax.plot([1,2,3])
+ fig.savefig('test.png')
+
+or by saving to a file handle::
+
+ import sys
+ fig.savefig(sys.stdout)
