Hi
I am developing on a Desktop install Ubuntu 9.04 machine with matplotlib
0.98.5.2,
and running the scripts on a Server install Ubuntu 8.10 machine with matplotlib
0.98.3.
I have found that the X axis layout for the same script varies between the two
machines.
Both have standard matplotlib installs using apt-get. I haven't made any tweaks.
Rather than go into great detail about the problem, please see the script below
and links to the resulting png files.
I hope the png files tell the story.

The plot produced by matplotlib 0.98.3 isn't what I want.
Id like the plot to go edge to edge on the x axis grid, as the matplotlib
0.98.3 version does.
Help and advise would be appreciated.
PS : I'm new to python & matplotlib
