Detailed Description

performs line-based thresholding for vtkTable data.

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.
