Section: Visualization Toolkit View Classes
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
obj = vtkParallelCoordinatesRepresentation
obj
is an instance of the vtkParallelCoordinatesRepresentation class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkParallelCoordinatesRepresentation = obj.NewInstance ()
vtkParallelCoordinatesRepresentation = obj.SafeDownCast (vtkObject o)
obj.ApplyViewTheme (vtkViewTheme theme)
- Apply the theme to this view. CellColor is used for line coloring
and titles. EdgeLabelColor is used for axis color. CellOpacity is
used for line opacity.
string = obj.GetHoverText (vtkView view, int x, int y)
- Returns the hover text at an x,y location.
int = obj.SetPositionAndSize (double position, double size)
- Change the position of the plot
int = obj.GetPositionAndSize (double position, double size)
- Change the position of the plot
obj.SetAxisTitles (vtkStringArray )

obj.SetPlotTitle (string )

int = obj.GetNumberOfAxes ()
- Get the number of axes in the plot
int = obj.GetNumberOfSamples ()
obj.SetNumberOfAxisLabels (int num)
- Set/Get the number of labels to display on each axis
int = obj.GetNumberOfAxisLabels ()
- Set/Get the number of labels to display on each axis
int = obj.SwapAxisPositions (int position1, int position2)
- Move an axis to a particular screen position. Using these
methods requires an Update() before they will work properly.
int = obj.SetXCoordinateOfPosition (int position, double xcoord)
- Move an axis to a particular screen position. Using these
methods requires an Update() before they will work properly.
double = obj.GetXCoordinateOfPosition (int axis)
- Move an axis to a particular screen position. Using these
methods requires an Update() before they will work properly.
obj.GetXCoordinatesOfPositions (double coords)
- Move an axis to a particular screen position. Using these
methods requires an Update() before they will work properly.
int = obj.GetPositionNearXCoordinate (double xcoord)
- Move an axis to a particular screen position. Using these
methods requires an Update() before they will work properly.
