vtkParallelCoordinatesRepresentation

Section: Visualization Toolkit View Classes

Usage

A parallel coordinates plot represents each variable in a multivariate data set as a separate axis. Individual samples of that data set are represented as a polyline that pass through each variable axis at positions that correspond to data values. vtkParallelCoordinatesRepresentation generates this plot when added to a vtkParallelCoordinatesView, which handles interaction and highlighting. Sample polylines can alternatively be represented as s-curves by enabling the UseCurves flag.

There are three selection modes: lasso, angle, and function. Lasso selection picks sample lines that pass through a polyline. Angle selection picks sample lines that have similar slope to a line segment. Function selection picks sample lines that are near a linear function defined on two variables. This function specified by passing two (x,y) variable value pairs.

All primitives are plotted in normalized view coordinates [0,1].

To create an instance of class vtkParallelCoordinatesRepresentation, simply invoke its constructor as follows
