* @brief Class for drawing an a bagplot.
|
|
*
|
|
*
|
|
* This class allows to draw a bagplot given three columns from
|
|
* a vtkTable. The first two columns will represent X,Y as it is for
|
|
* vtkPlotPoints. The third one will have to specify if the density
|
|
* assigned to each point (generally obtained by the
|
|
* vtkHighestDensityRegionsStatistics filter).
|
|
* Points are drawn in a plot points fashion and 2 convex hull polygons
|
|
* are drawn around the median and the 3 quartile of the density field.
