[SciPy-user] Error message I don't understand

[Christian Meesters]

Hi Robert,

After tinkering a bit with my code and the actual data I discovered my 
mistake. Instead of having, say on the x-axis, data like 0,1,2,3,... I 
had 10,9,8,7,6 ... . Same on the y-axis. I don't quite understand how 
that could raise this error message, but at least the script is running 
now.

Anyhow, even though it turned out to be just my stupidity: Thank you 
for helping me.

Cheers,
Christian
