Heatmap

The view can be accessed either via the “Open view” action on the executed node or on KNIME Hub.
In the node configuration, you can choose the columns to use for horizontal and vertical dimensions and enable certain controls, which are then available in the view. This includes the ability to choose different aggregation methods and the column with the data to color map or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the Heatmap in the desired shape quickly.
