Re: [Matplotlib-users] Text outside the graphs "box"
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...

Hello again I tried:
plt.figtext(0, 1.2, r'$F(x)=p*\frac{1}{s1\sqrt{2\pi}}$', fontsize=20)
but then the text is outside the printed area and therefore not
displayed. Does that mean that the printed area has to be changed as
well?

[Matplotlib-users] Cannot obtain dvipng version
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.

It is a security feature. The apache user is limited by selinux. I
don't know how to address this, but selinux is where you should look.
Ben Root
PS - Don't succum to the temptation to simply turn off selinux. There
are easy ways to create exception modules using sealert and other
tools. Selinux is a very important part of the security mechanisms
for Linux.

But the documentation says the following.

Even if 10 are being drawn, I think there would only be 9 subticks
*between*the major ticks because the first subtick is on a major tick.
Am I wrong?
I'm using matplotlib version 0.99.3.
