Density Plot

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 enable certain controls, which are then available in the view. This includes the ability to choose a dimension column and a condition column or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the density plot in the desired shape quickly.

Missing as well as NaN (not a number) values in the dimension column are ignored. If a condition column is chosen, a category is ignored when all corresponding cells in the dimension column are ignored. The density is computed via kernel density estimation with a gaussian kernel. The bandwidth for the kernel can either be set to a specific value or computed with Scott's rule of thumb (see R's bw.nrd ).
