There is a histogram demo available at a gallery site of matplotlib at

http://matplotlib.sourceforge.net/examples/api/histogram_demo.html.

I downloaded and ran this program, but it failed to draw the histogram
with some error messages as follows.

---
$ python histogram_demo.py
Exception in Tkinter callback

TclError

When, in addition, I ran it, a window titled 'Figure 1' appeared. But, it displays nothing.

It's possible to avoid that problem by downgrading python-tk to 2.5.2 version

I'm pretty sure that this is a matplotlib bug rather than an Ubuntu one - I'll see if I can submit it to the SciPy people.

The bug is fixed in matplotlib 0.98.5.2-1ubuntu2 (combined with python-tk 2.6.1-0ubuntu2). The histogram demo is drawn without errors.
