<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkParallelCoordinatesActor generates a parallel coordinates plot from an input field (i.e., vtkDataObject). Parallel coordinates represent N-dimensional data by using a set of N parallel axes (not orthogonal like the usual x-y-z Cartesian axes). Each N-dimensional point is plotted as a polyline, were each of the N components of the point lie on one of the N axes, and the components are connected by straight lines.</p>
<p>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, attributes, number of ticks on the axes, etc.</p>
<p>Set the text property/attributes of the title and the labels through the vtkTextProperty objects associated to this actor.</p>
<p>To create an instance of class vtkParallelCoordinatesActor, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkParallelCoordinatesActor
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkParallelCoordinatesActor has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, <code>obj</code> is an instance of the vtkParallelCoordinatesActor class. </p>
