countour problem with 0.87

Community matplotlib-users

Dear friends,

I just upgrade matplotlib from 0.83.2 to 0.87 under WinXP, Python 2.3.5,
Numeric 23.8. I find out that all my plots using contour function do not
work anymore. I also tried the examples: contour_demo.py,
contourf_demo.py and contour_image.py. All of them do not work with the
following error message:

   File "contour_demo.py", line 26, in ?
     levels, colls = contour(X, Y, Z)
TypeError: unpack non-sequence

Anyone has any clue in fixing this problem?

Best regards,
Chris

Chris: Contour now returns a single object, so replace all your calls with something like
CS = contour(X,Y,Z)

P.S. You must not have updated the examples, because the ones that come with maplotlib 0.87 do work.

Thanks Jeff for quick input. It is working well for me now.

For the examples, I download from the link on the homepage which still points to http://matplotlib.sourceforge.net/matplotlib_examples_0.83.2.zip
