Inputs:

in : table

Input data

Outputs:

out : table

Heatmap data

Configuration:

X data column:

Select X axis data

Y data column:

Select Y axis data

Z data column:

The data points of the z data are placed in bins according to the cooresponding values of x and y. They are then reduced to a single bin value using the selected reduction function. For “Count (histogram)” no z data column is needed.

Reduction function:

A function used on all the z data points in a bin. For “Count (histogram)” no z data column is needed.

X Bins:

Number of bins on the x axis

Y Bins:

Number of bins on the y axis

Auto range

When checked, use data range as histogram range

X min:

Set minimum X value

X max:

Set maximum X value

Y min:

Set minimum Y value

Y max:

Set maximum Y value
