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.

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

Histogram data

Configuration:
Data column: (data_column)
Column to create histogram for.
Weights column: (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: (bins)
Number of bins.
Auto range (auto_range)
When checked, use data range as histogram range.
X min: (x_min)
Minimum x value.
X max: (x_max)
Maximum x value.
Density (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.
