[SciPy-user] histogram bug ?

[Gary]

WinXP, scipy_core version 0.9.0.1713

tried to call scipy.histogram with the default bins=10. See below.


It works ok if I make my own bins.



========================================

In [288]: f
Out[288]:
array([  46.,   59.,   77.,   87.,   50.,   97.,   84.,   73.,  100.,
         34.,   86.,   67.,   68.,  100.,   74.,   81.,   94.,   66.,
         52.,   66.,   69.,   54.,   85.,   97.,   31.,   49.])

In [289]: scipy.histogram(f)
