I did some more digging and I think I have a hypothesis for what is
happening.
There is only one main difference between a call to .drawstates() and
.readshapefiles() with respect to loading and plotting data. .drawstates()
loads *only* the line segments that coincide with the defined map

Hello,
Attached is a test script to produce low and high resolution (data-wise)
images in multiple formats. You can change the dpi in the script, however,
I have not noticed any significant difference. It also appears that the
data resolution doesn't impact the size of the artifact as much as I
If possible, can you try the latest svn version and see if it makes
any difference?
Also, see if increasing the dpi helps, i.e.,
savefig(..., dpi=150)
Given the nature of the rasterization, I'm not sure if we can
completely avoid the white gap for low dpi settings.
But the displacement issue you
Markus,
Looking again at your image, I realized that you are probably using real
data, not simulated data, therefore you can't easily use a higher grid
resolution.
So, I created a test script to examine this. I have found that there is
definitely a difference between filetypes. In my test scrip
Hi,

I have been doing some testing with pcolor() and pcolormesh() with regards
to rasterization. I can not see a displacement when choosing between
different file types or with setting rasterized to be True or False. What I
have noticed is a half grid-space displacement between pcolor() and
pcolormes
Hi,
Using the SVN version the following example fails with:
File "/usr/local/lib/python2.6/dist-packages/matplotlib/colors.py", line
815, in inverse
raise ValueError("Inversion requires valid vmax > vmin")
ValueError: Inversion requires valid vmax > vmin
This was introduced in svn revision
