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.

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.
