(x, weights, bins=10, range=None, flow=False)[source]¶ Histogram data with multiple weight variations and fixed width bins.
 Parameters
x (array_like) – data to histogram.
weights (array_like) – The weight variations for the elements of
x
, first dimension is the length ofx
, second dimension is the number of weights variations.bins (int) – The number of bins.
range ((float, float), optional) – The minimum and maximumm of the histogram axis.
flow (bool) – If True, the under and overflow bin contents are added to the first and last bins, respectively.
 Returns
numpy.ndarray
– The bin counts.numpy.ndarray
– The standard error of each bin count, \(\sqrt{\sum_i w_i^2}\).
Examples
Multiple histograms of
x
with 50 bins between 0 and 100; using 20 different weight variations:>>> x = np.random.randn(10000) >>> twenty_weights = np.random.rand(x.shape[0], 20) >>> h, err = fix1dmw(x, w, bins=50, range=(3, 3))
h
anderr
are now shape(50, 20)
. Each column represents the histogram of the data using its respective weight.
