Heatmap calculation¶
This node calculates a 2D histogram or other heatmap of a given signal.
The output consists of bin edges and bin values and can for instance be used in a heatmap plot in the node Figure.
This node ignores any rows in the input where one or more of the selected columns are masked.
- Input ports:
in: table
Input data
- Output ports:
out: table
Heatmap data
- Configuration:
- X data column: (x_data_column)
- Select X axis data
- Y data column: (y_data_column)
- Select Y axis data
- Z data column: (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: (reduction)
- A function used on all the z data points in a bin. For “Count (histogram)” no z data column is needed.
- X Bins: (x_bins)
- Number of bins on the x axis
- Y Bins: (y_bins)
- Number of bins on the y axis
- Auto range (auto_range)
- When checked, use data range as histogram range
- X min: (x_min)
- Set minimum X value
- X max: (x_max)
- Set maximum X value
- Y min: (y_min)
- Set minimum Y value
- Y max: (y_max)
- Set maximum Y value
