matplotlib: TypeError: a float is required

[Andi Clemens]

Sorry but english isn't my native language so I don't really get what 
you are trying to tell me, it took me quite a long time to figure out 
what SFA means (I guess it is Sweet Fanny Adams => nothing at all).

All examples were taken from the matplotlib-homepage but they won't work 
on my installation and I don't know why.
You point out that "left and height are Numeric arrays", and that is 
exactly what they are, so what am I missing?

I tried nearly 10 examples from different websites and tutorials and 
none of them worked!
So I don't think I'm doing something wrong, or am I?
