Histogram calculation

Calculate the histogram of a given signal.

Documentation

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.

table

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.
