Hi Christian,


I've been using the Rectangle class in patches to plot unfilled 
rectangles. Circle and Polygon classes are also available that you 
may find useful.

You can control the filling, the colors of the faces and edges, and 
the thickness of the edges.

Here's an example for an unfilled red rectangle.


from matplotlib.patches import Rectangle
...
...
fig=figure(figsize=(W,H))
ax = fig.add_axes([left,bottom,width,height])        
p=Rectangle([x,y], 4.0, 0.6, fill=False, linewidth=1, edgecolor="red")
ax.add_patch(p)


-Cheers
