Problem using contour(....,fmt='1.3f')

Hi all,
I'm still trying to analyse my data using the contour directive. When adding
fmt='1.3f' to the arguments, here's what happens:

In [25]:contour(r[0:zmax],z[0:zmax],rho[0:zmax],30,fmt = '1.3f')

    689 collections.append(col)

TypeError: not all arguments converted during string formatting

Any hint ?

Thanks in advance,
cheers,

Nicolas: I believe that should be fmt='%1.3f'.

Jeff,
once again, you were tight : thanks for your support !

May I suggest that the documentation for contour() contains fmt='%1.3f'
instead of fmt='1.3f' ?

cheers,
Nicolas

Someone beat me to it - it already reads that way in CVS.

Nope... see lib/matplotlib/contour.py, current cvs version, line 627.
