Hello,

I am having a problem with the colorbar when plotting a constant field.

The small script below will generate a plot that is a solid blue image with a 
solid blue colorbar.  However
the label on the colorbar is garbage.  There is no way to read the label to 
determine what value the image represents.

Has anyone else had a similar problem?  How do I fix it?

I am running matplotlib version 1.0.1 installed from macports -- 
py26-matplotlib 
@1.0.1_3+tkinter

Thanks.

---

import matplotlib.pyplot as plt
import numpy as np

C = np.matrix('1 1 1; 1 1 1; 1 1 1')

plt.imshow(C)
plt.colorbar()
plt.show()
