vtkBivariateLinearTableThreshold

Section: Visualization Toolkit Infovis Classes

Usage

Class for filtering the rows of a two numeric columns of a vtkTable. The columns are treated as the two variables of a line. This filter will then iterate through the rows of the table determining if X,Y values pairs are above/below/between/near one or more lines.

The "between" mode checks to see if a row is contained within the convex hull of all of the specified lines. The "near" mode checks if a row is within a distance threshold two one of the specified lines. This class is used in conjunction with various plotting classes, so it is useful to rescale the X,Y axes to a particular range of values. Distance comparisons can be performed in the scaled space by setting the CustomRanges ivar and enabling UseNormalizedDistance.

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

  obj = vtkBivariateLinearTableThreshold
