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.

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.

Density

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.
