Histogram (Labs)

A histogram visualization node. The view can be accessed either via the “interactive view” action on the executed node or on KNIME WebPortal.
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 fast in the desired shape. Missing values as well as NaN (not a number) or infinite values can be handled differently according to the configuration.

Note, this node is currently under development. Future versions of the node might have improved or changed functionality. Interactivity between multiple views is currently only possible with views also coming from this labs extension.
