matplotlib-users Mailing List for matplotlib

Hi, I'm trying to do some CAD type things with Matplotlib. I'm using python
2.4 with both PS and GTK backends in WinXP. Specifically, I'm trying to
find distances between objects (lines, polygons, circles), so I'd like to
extract all the elements/lines/polygons/arcs/circles in an axis, but I don't
see how to do that. 
 
Also, I need to draw arcs, but it seems I can only do that by directly
manipulating the renderer. I'm trying to get everything done using only the
pylab interface. I tried creating a RendererPS directly, but it took some
funny arguments (eg a StreamIO) which I wasn't sure what to do with.
 
 
Any suggestions would be great.
Thanks
Michael

just set the limits of your axes with xlim/ylim or set_ylim/set_xlim
For example:
y = N.arange(10)
plot(y)
ylim(y[-1],y[0])

Hi,
What is the method used to flip axes in X and/or Y direction in the 
matplotlib API? that is, to plot something with values from positive to 
negative instead of the contrary?
Maybe it's me being dense :), but I can't find how to do it.
Thanks!

Thanks a lot. I uninstalled 1.01b1 and installed 0.9.8 and everything 
workes perfectly.
Thanks again,
Massimo
