Histogram calculation

../../../../_images/histogram_calculation.svg

This node takes a table and calculates a histogram from one of its columns.

The output consists of bin edges and bin values and can for instance be used in a histogram plot in the node Figure from Table.

Masked values in the data column are ignored. Masked values in the weights column are treated as 1.

Outputs:

Histogram data

Configuration:

data_column
Column to create histogram for.
weights_column
If you choose a weights column, each value in the data column only contributes its associated weight towards the bin count, instead of 1.
bins
Number of bins.
auto_range
When checked, use data range as histogram range.
x_min
Minimum x value.
x_max
Maximum x value.
normed
When checked, the result is the value of the probability density function at each bin, normalized such that the integral of the histogram is 1.
