[matplotlib-devel] Histogram bug introduced in r8218

2010-05-03 Thread Tony S Yu 
It seems that changes introduced in r8218 drastically changed how `hist` 
handles Python lists.

For example, the histogram given by the following snippet, works as expected:

>>> x = np.random.randn(100)
>>> plt.hist(x)

However, if you pass a 1D list to `hist`, the 1D list is cast to a list of 
length-1 arrays---each treated as a separate histogram. Continuing the above 
code, check the results of the following:

>>> plt.hist(list(x))

I assume that this behavior is unintended, right?
