Hi all,
When creating a new colormap, with a script based on the example given here:
http://www.scipy.org/Cookbook/Matplotlib/Show_colormaps
When plotting the data, and when adding the colobar, I get this error:
In [27]: Exception in Tkinter callback
Traceback (most recent call last):

TypeError: data must be convertable to an array
When I don't change the example from the cookbook, I still get the same
error, and no image. Previously, I didn't get this error. I'm using
Python 2.6 and MPL 0.99.0 on Ubuntu 9.10.
Any help would be great!
Marius.
