calculate_bin_edges
(a, bins=10, range=None, weights=None)[source]¶ Calculate histogram bin edges like
numpy.histogram_bin_edges
. Parameters
 aarray_like
Input data. The bin edges are calculated over the flattened array.
 bins
int
,list
, orstr
, optional If
bins
is an int, it is the number of bins. If it is a list it is taken to be the bin edges. If it is a string, it must be one of ‘blocks’, ‘knuth’, ‘scott’ or ‘freedman’. Seehistogram
for a description of each method. range
tuple
orNone
, optional The minimum and maximum range for the histogram. If not specified, it will be (a.min(), a.max()). However, if bins is a list it is returned unmodified regardless of the range argument.
 weightsarray_like, optional
An array the same shape as
a
. If given, the histogram accumulates the value of the weight corresponding toa
instead of returning the count of values. This argument does not affect determination of bin edges, though they may be used in the future as new methods are added.
