vtkSpiderPlotActor

Section: Visualization Toolkit Hybrid Classes

Usage

vtkSpiderPlotActor generates a spider plot from an input field (i.e., vtkDataObject). A spider plot represents N-dimensional data by using a set of N axes that originate from the center of a circle, and form the spokes of a wheel (like a spider web). Each N-dimensional point is plotted as a polyline that forms a closed polygon; the vertices of the polygon are plotted against the radial axes.

To use this class, you must specify an input data object. You'll probably also want to specify the position of the plot be setting the Position and Position2 instance variables, which define a rectangle in which the plot lies. Another important parameter is the IndependentVariables ivar, which tells the instance how to interpret the field data (independent variables as the rows or columns of the field). There are also many other instance variables that control the look of the plot includes its title and legend.

Set the text property/attributes of the title and the labels through the vtkTextProperty objects associated with these components.

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

  obj = vtkSpiderPlotActor
