Statistics View

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 you want to display. Only numeric and text based columns are supported.
The configuration also offers a preview of the table, which should help to get the statistics in the desired shape quickly.
This node accepts either numeric or nominal based columns, while all other types will be ignored. Note that in case nominal columns, the calculated numeric statistics refer to the string length. All statistics calculation will ignore missing and NaN values. For first and last element in a nominal dimension the lexicographic order will be used.

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