[Matplotlib-users] contour legend

2008-10-17 Thread Jakub Urban 
Hello everybody!
 
I'm trying to make a contour plot and add a legend for it. The code is
basically
---
from numpy import *
from matplotlib.pyplot import *
# put anything into x,y,z arrays
ctr = contour(x,y,z) # plots ok contours of z(x,y)
ctr.collections[0].set_label('z')
legend()
show()
---
The legend() command produces an error (see below). What's wrong with this?
 
Thanks for any help
