astroML.density_estimation.histogram(a, bins=10, range=None, **kwargs)[source]

Deprecated since version 0.4: The histogram function is deprecated and may be removed in a future version. Use astropy.stats.histogram instead.

Enhanced histogram

This is a histogram function that enables the use of more sophisticated algorithms for determining bins. Aside from the bins argument allowing a string specified how bins are computed, the parameters are the same as numpy.histogram().


array of data to be histogrammed

binsint or list or str (optional)

If bins is a string, then it must be one of: ‘blocks’ : use bayesian blocks for dynamic bin widths ‘knuth’ : use Knuth’s rule to determine bins ‘scotts’ : use Scott’s rule to determine bins ‘freedman’ : use the Freedman-diaconis rule to determine bins

rangetuple or None (optional)

the minimum and maximum range for the histogram. If not specified, it will be (x.min(), x.max())

other keyword arguments are described in numpy.hist().


The values of the histogram. See normed and weights for a description of the possible semantics.

bin_edgesarray of dtype float

Return the bin edges (length(hist)+1).
