Hi there, I am not sure whether I am the only one to experience that but
on my new FEDORA 12 box GTK+ is shipped with the following structure
for the headers : /usr/include/gtk-1.2/gtk/gtk.h
This does not seem to be expected by matplotlib setup.cfg , or am I
missing something?
thanks,

thanks Eric! Could you provide me with an executive summary as to

Also, I tried to add a colorbar but failed. What is the correct invocation?

hello,
I have a function, which I am plotting. I want to add a line positioned
at, say, the mean of the function, so I want to do plot([x,x],[y0,y1]).
In order to get y0, and y1, my brute force trial and error browsing of

I could test that

works,

I would like to know if there is an easy to invert a axis (specifically

That did it.

To achieve this, I tried using :
