Usage
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.
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.
Set the text property/attributes of the title and the labels
through the vtkTextProperty objects associated to this
actor.
To create an instance of class vtkParallelCoordinatesActor,
simply invoke its constructor as follows
obj = vtkParallelCoordinatesActor
Methods
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,
obj is an instance of the vtkParallelCoordinatesActor class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkParallelCoordinatesActor = obj.NewInstance ()
* vtkParallelCoordinatesActor = obj.SafeDownCast (vtkObject
o)
* obj.SetIndependentVariables (int ) - Specify whether to
use the rows or columns as independent variables. If
columns, then each row represents a separate point. If
rows, then each column represents a separate point.
* int = obj.GetIndependentVariablesMinValue () - Specify
whether to use the rows or columns as independent
variables. If columns, then each row represents a separate
point. If rows, then each column represents a separate
point.
* int = obj.GetIndependentVariablesMaxValue () - Specify
whether to use the rows or columns as independent
variables. If columns, then each row represents a separate
point. If rows, then each column represents a separate
point.
* int = obj.GetIndependentVariables () - Specify whether to
use the rows or columns as independent variables. If
columns, then each row represents a separate point. If
rows, then each column represents a separate point.
* obj.SetIndependentVariablesToColumns () - Specify whether
to use the rows or columns as independent variables. If
columns, then each row represents a separate point. If
rows, then each column represents a separate point.
* obj.SetIndependentVariablesToRows () - Specify whether to
use the rows or columns as independent variables. If
columns, then each row represents a separate point. If
rows, then each column represents a separate point.
* obj.SetTitle (string ) - Set/Get the title of the parallel
coordinates plot.
* string = obj.GetTitle () - Set/Get the title of the
parallel coordinates plot.
* obj.SetNumberOfLabels (int ) - Set/Get the number of
annotation labels to show along each axis. This values is
a suggestion: the number of labels may vary depending on
the particulars of the data.
* int = obj.GetNumberOfLabelsMinValue () - Set/Get the
number of annotation labels to show along each axis. This
values is a suggestion: the number of labels may vary
depending on the particulars of the data.
* int = obj.GetNumberOfLabelsMaxValue () - Set/Get the
number of annotation labels to show along each axis. This
values is a suggestion: the number of labels may vary
depending on the particulars of the data.
* int = obj.GetNumberOfLabels () - Set/Get the number of
annotation labels to show along each axis. This values is
a suggestion: the number of labels may vary depending on
the particulars of the data.
* obj.SetLabelFormat (string ) - Set/Get the format with
which to print the labels on the axes.
* string = obj.GetLabelFormat () - Set/Get the format with
which to print the labels on the axes.
* obj.SetTitleTextProperty (vtkTextProperty p) - Set/Get the
title text property.
* vtkTextProperty = obj.GetTitleTextProperty () - Set/Get
the title text property.
* obj.SetLabelTextProperty (vtkTextProperty p) - Set/Get the
labels text property.
* vtkTextProperty = obj.GetLabelTextProperty () - Set/Get
the labels text property.
* int = obj.RenderOpaqueGeometry (vtkViewport ) - Draw the
parallel coordinates plot.
* int = obj.RenderOverlay (vtkViewport ) - Draw the parallel
coordinates plot.
* int = obj.RenderTranslucentPolygonalGeometry (vtkViewport
) - Does this prop have some translucent polygonal
geometry?
* int = obj.HasTranslucentPolygonalGeometry () - Does this
prop have some translucent polygonal geometry?
* obj.SetInput (vtkDataObject ) - Set the input to the
parallel coordinates actor.
* vtkDataObject = obj.GetInput () - Remove a dataset from
the list of data to append.
* obj.ReleaseGraphicsResources (vtkWindow ) - Release any
graphics resources that are being consumed by this actor.
The parameter window could be used to determine which
graphic resources to release.
