Hi All:
I'm using the following code to create and display an image with a
colorbar. Later on, I read data from a file and update the image.
How do I refresh the colorbar to match this new data? Uncommenting the
line in my "ReadFromFile" call below generates a new colorbar. I'd just
like to replace the existing one to match the new data.
I'm using Python 2.5.2, wx 2.8.7.1, and Matplotlib 0.98.5.2 on win32.
THANXS
