I'm trying to plot a circle AND flip an axis of the plot, but this leads
to an inverted circle (diamond) being drawn. Is there any way to do this
'neatly' (besides, for example, manually editing the axis labels or using
a many-sided polygon to fake a circle)? Note that the circle renders
Hi,
I've a little problem with date conversion. I have a csv file which looks
like :
Data,Valor

12/01/2007, 6,659903000

I try to get date using function strpdate2num in load doing this :
from pylab import datestr2num, load
def comma_nb2float(A):
You can just pass a path to savefig, e.g.:
savefig(/home/me/test.png)
(The format is automatically determined from the extension). If you
want to know which formats are supported by which backends, you can have
a look at FILETYPES in the source tree here:

If I am reading this right, according to the svn log, you fixed this in

This bug is that many font files were being opened than needed, but they
were still all getting closed.
Much earlier, someone else fixed a bug where they weren't getting closed
at all.

I just upgraded and checked -- the bug still exists in 0.91.1. I'm
afraid I don't know whether it has been fixed by r4633 or not.

The patch for r4633 is pretty simple, so you could test it without
needing to check out from SVN or build your own matplotlib etc.
Open the file font_manager.py, which should live in
%PYTHONPATH%/Lib/site-packages/matplotlib. Around line 681, you'll
find the function:

The r4633 patch fixes the problem indeed. Thanks for your help!!

I think the problem might be related to using numarray and not numpy.

As of matplotlib 0.91.1, savefig() supports saving to a file-like object
