Parallel Coordinates Plot

KNIME Dynamically Created JavaScript Nodes version 4.3.0.v202011211957 by KNIME AG, Zurich, Switzerland

A parallel coordinates plot displays multidimensional data as polylines over multiple parallel and evenly spaced axes. More information is available on Wikipedia.

Rows that contain missing values, if present, are treated in accordance with the chosen in the dialog or in interactive view option.

The node supports custom CSS styling. You can simply put CSS rules into a single string and set it as a flow variable 'customCSS' in the node configuration dialog. You will find the list of available classes and their description on our documentation page.
