Histogram

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 binning method and enable certain controls, which are then available in the view. This includes the ability to choose different columns for the dimension or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the histogram in the desired shape quickly.
Missing values as well as NaN (not a number) or infinite values can be handled differently according to the configuration.

Interactivity between multiple views is currently only possible for views coming from the KNIME Views extension.
