Hi,
I'm having a problem when importing pylab in a python CGI script to generate
some dynamic graphs for a web page.
As soon as I import pylab, my script will fail, and I have no idea why.
As an example, i can have 1x1 black png file, loaded from a script like
thus:
#!/usr/bin/env python

I'm fairly new to HTML, and I can't seem to see any meaningful errors in
Firebug. Anyone have any experience with an error like this?
This is not HTML, it's a CGi, so a script executed
Hi Sandro,
Thanks for the tip.
In checking the HTTP logs, I found that the apache user couldn't create a
.matplotlib directory (as it had no home dir) so i used the environment
variable MPLCONFIGDIR to point to somewhere meaningful, then I found that to
import pylab I needed a DISPLAY variable

We have uploaded a bugfix release of the matplotlib-0.99 branch.
Source and binaries are available for download from
https://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-0.99.3
This release fixes many minor and at least one critical bug in our
path simplification algorithm.
Hello everyone!
Here's my first (bout not last) post:

Hi all, I updated to version 99.1.1 and I'm still getting the error

As Eric told, you need to build it from the svn. Unfortunately, no
released version (I believe) includes this feature.
http://matplotlib.sourceforge.net/faq/installing_faq.html#install-from-svn
Anyhow, the patch for box-forced involves only a few lines of
change. You may consider to apply it by

That's doing it, thought there might be an internal way within matplotlib,
but I could figure one.
I'm quite confused with the canvas, dpi, ...

I'm having trouble getting a multi-yaxis plot looks right. See:

Hi,
Is there a way to change (and maybe remove) the background color (gray
by default) of axis in mplot3d graphics ?
Thanks,

Denis,
There are probably other ways, but the one that I know off the top of my
head is done at the savefig() function. If you want to remove the
background entirely, you can specify the keyword argument transparent=True.
You can change the color using the facecolor keyword argument. You can

two separate modules, axes_grid1 and axisartist (axes_grid

Thanks for your answer.
Actually, options for savefig seem to only operate on 2D axes whereas
I'm trying to change the color of 3D axes (x,y,z) which, by default,
have a grid with a gray background.
I manage to remove the grid lines but not the background color.

You can make an x vector and a y array, so that the first dimension of y is
the same length as x:

Howard,
Are you trying to plot 4 lines with the same y-axis or with two or more
y-axes? I only ask because the values of your 5th column are many orders of
magnitude smaller than the values of the other ys.
If you want multiple y-axes on the same plot, then you might want to look at

You may want to look into Numpy's genfromtxt() or loadtxt() functions. They
