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
Methods
The class vtkSpiderPlotActor 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 vtkSpiderPlotActor class.
* string = obj.GetClassName () - Standard methods for type
information and printing.
* int = obj.IsA (string name) - Standard methods for type
information and printing.
* vtkSpiderPlotActor = obj.NewInstance () - Standard methods
for type information and printing.
* vtkSpiderPlotActor = obj.SafeDownCast (vtkObject o) -
Standard methods for type information and printing.
* obj.SetInput (vtkDataObject ) - Set the input to the
spider plot actor.
* vtkDataObject = obj.GetInput () - Get the input data
object to this actor.
* 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.SetTitleVisibility (int ) - Enable/Disable the display
of a plot title.
* int = obj.GetTitleVisibility () - Enable/Disable the
display of a plot title.
* obj.TitleVisibilityOn () - Enable/Disable the display of a
plot title.
* obj.TitleVisibilityOff () - Enable/Disable the display of
a plot title.
* obj.SetTitle (string ) - Set/Get the title of the spider
plot.
* string = obj.GetTitle () - Set/Get the title of the spider
plot.
* obj.SetTitleTextProperty (vtkTextProperty p) - Set/Get the
title text property.
* vtkTextProperty = obj.GetTitleTextProperty () - Set/Get
the title text property.
* obj.SetLabelVisibility (int )
* int = obj.GetLabelVisibility ()
* obj.LabelVisibilityOn ()
* obj.LabelVisibilityOff ()
* obj.SetLabelTextProperty (vtkTextProperty p) - Enable/
Disable the creation of a legend. If on, the legend labels
will be created automatically unless the per plot legend
symbol has been set.
* vtkTextProperty = obj.GetLabelTextProperty () - Enable/
Disable the creation of a legend. If on, the legend labels
will be created automatically unless the per plot legend
symbol has been set.
* obj.SetNumberOfRings (int ) - Specify the number of
circumferential rings. If set to zero, then none will be
shown; othewise the specified number will be shown.
* int = obj.GetNumberOfRingsMinValue () - Specify the number
of circumferential rings. If set to zero, then none will
be shown; othewise the specified number will be shown.
* int = obj.GetNumberOfRingsMaxValue () - Specify the number
of circumferential rings. If set to zero, then none will
be shown; othewise the specified number will be shown.
* int = obj.GetNumberOfRings () - Specify the number of
circumferential rings. If set to zero, then none will be
shown; othewise the specified number will be shown.
* obj.SetAxisLabel (int i, string ) - Specify the names of
the radial spokes (i.e., the radial axes). If not
specified, then an integer number is automatically
generated.
* string = obj.GetAxisLabel (int i) - Specify the names of
the radial spokes (i.e., the radial axes). If not
specified, then an integer number is automatically
generated.
* obj.SetAxisRange (int i, double min, double max) - Specify
the range of data on each radial axis. If not specified,
then the range is computed automatically.
* obj.SetAxisRange (int i, double range[2]) - Specify the
range of data on each radial axis. If not specified, then
the range is computed automatically.
* obj.GetAxisRange (int i, double range[2]) - Specify the
range of data on each radial axis. If not specified, then
the range is computed automatically.
* obj.SetPlotColor (int i, double r, double g, double b) -
Specify colors for each plot. If not specified, they are
automatically generated.
* obj.SetPlotColor (int i, double color[3]) - Specify colors
for each plot. If not specified, they are automatically
generated.
* obj.SetLegendVisibility (int ) - Enable/Disable the
creation of a legend. If on, the legend labels will be
created automatically unless the per plot legend symbol
has been set.
* int = obj.GetLegendVisibility () - Enable/Disable the
creation of a legend. If on, the legend labels will be
created automatically unless the per plot legend symbol
has been set.
