Parallel Coordinates view

Parallel Coordinates view

Parallel coordinates works by having vertical axis per data column and each row is displayed as a series of connected points along the axes. Using our innate pattern-recognition abilities, it enables spotting multivariate relations in a blink. Thanks to its unique density-based approach to avoid overplotting, and the choice between straight and curved geometries, relations and trends emerge immediately.

At the bottom of the user interface, you will find the Parallel Coordinates view that corresponds to the chosen settings in the Configuration and Axes panels. Each item is represented by a polyline or polycurve.

Moving the mouse over a shape will display a pop-up window (also called a tooltip) that shows the values configured in the "Labels" section of the "Configuration" panel.

Probing and selection

Selection can be performed by clicking on a shape. Adding to or removing items from the selection can be done by holding the Ctrl key down while clicking on shapes.

Multiple adjoining items can be selected using a rubberband which is activated by dragging the mouse while holding down the Alt key.


Items can be filtered by using the range sliders embedded in the Parallel Coordinates view. The range of an attribute can be specified by moving the handles on the top and bottom of the corresponding range slider. Items whose value for that attribute falls outside of the specified range, are filtered out and can not be interacted with anymore. Their "ghosts" remain visible though and they appear greyed-out. Use a combination of range sliders to dynamically formulate complex queries.

Axes reordering

An axis can be moved to a different position by dragging its label and dropping it at the desired position. Automatic reordering can be performed through the Axes panel.
