You can send it to me directly offlist and I'll merge it into the main
tree. Just make sure to put matplotlib in the subject header to get
past my spam filter...
Thanks!

Hello,
I've just encountered the same situation with SVG rendering where I =
repeatedly generate a changed SVG plot and only the first time does it =
render properly. I traced the problem to the SVG renderer failing to =
include "ClipPath" information in generated SVG files after the first =
one, and fixed it in my case by changing backend_svg.RendererSVG to deal =
with _clipd as self._clipd in both its __init__ method (i.e., =
initialized to {}) and its _get_gc_clip_svg method (i.e., _clipd =
changed to self._clipd). Just before RendererSVG is defined, _clipd is =
declared as a module-scope entity, and this is the problem, so comment =
it out...
If anyone is interested in my modified backend_svg.py please let me know =
where to send it.
Regards,
Norm Petterson

 Subject: [Matplotlib-users] [Possible BUG:] SVG renderer;
 Hi, I've run into a problem using matplotlib renderer to generate =
files. My example is huge, so I implement it in another way to give the =
idea.
 - o - o - o - o - o - o - o - o - o - o - o - o - o - o=20
 from matplotlib.matlab import *
 def draw_box(i):
 root =3D axes([0,0,1,1])
 root.bar(.2,.5,.5,.2)
 root.text(.2, .1, "Give me a box %02i"%i)
 xlim(0,1)
 ylim(0,1)
 savefig("c:\\svg\\%02i.svg"%i)
 for i in xrange(1,10):
 clf()
 draw_box(i)
 - o - o - o - o - o - o - o - o - o - o - o - o - o - o=20
 The resulting files are generated, yet except the first one, all the =
rest miss the bar();
 BUT, if I change the format to .png, no problem exists.
 Is it a bug? or am I doing it right?
 Much appreciated if you can point the problem out.
