ParallelCoordinates

Description

The ParallelCoordinates component is a parallel coordinates chart.

Comments

The component is implemented by the ParallelCoordinates class.

A parallel coordinates chart is used to graphically present data in an n-dimensional space. This chart shows n vertical and equally spaced parallel lines. A point in n-dimensional space is represented as a polyline with vertices on the parallel axes. Point coordinates correspond to positions of vertices on each axis.

The component enables the user to set up plot area, vertical axes and lines for a parallel coordinates chart.

Example

The component may look as follows:
