matplotlib-users Mailing List for matplotlib

I am trying use matplotlib on CentOS through a PHP script. If I run it on
the command line it works fine and generates a PNG figure. If I run with
another user,

sudo -u apache python filename.py

it gives error: Cannot obtain dvipng version.

Any ideas? I search the net but no answers. It looks like a bug? In the
script I am using TeX.

rc('text', usetex=True)

Texlive and dvipng are installed and paths are set correctly.

How is the space between the axis and the outer margins of a figure defined?
How much space is between the upper most plot and the upper end of the figure?
This is the space e.g for the titles etc. but can this be space be increased?

Or how can a some text be placed above the axis but with a lot of space?
I hope it is now clearer...

It is now fixed in v1.0.x and master on github.

It's a bug.
