Function Details

histogram(data, nbins, range=None)

Create a histogram. Comes from Konrad Hinsen: Scientific Python

Parameters:

data ([any]) - data list or array
nbins (int) - number of bins
range ((float, float) OR None) - data range to create histogram from (min val, max val)

Returns: array: array (2 x len(data) ) with start of bin and witdh of bin.

density(x, nBins, range=None, steps=1, hist=0)

returns the normalized histogram of x:

 density( data, nBins [,range=None, steps=1, hist=0|1] ) -> array

Parameters:

x ([any]) - data list or array
nBins (int) - number of bins
range ((float, float) OR None) - data range to create histogram from (min val, max val)
steps (1|0) - 1: histogram appears as a discrete graph (default 1)
hist (1|0) - 0: normalize histogram (default 0)

Returns: array: array (2 x len(data) ) with start of bin and witdh of bin.
