class TParallelCoordVar: public TNamed, public TAttLine, public TAttFill


Class containing a variable for the TParallelCoord.

Options can be defined each axis separatly using the right mouse click. These options can be applied to every axes using the editor.

  • Axis width: If set to 0, the axis is simply a line. If higher, a color histogram is drawn on the axis.
  • Axis histogram height: If not 0, a usual bar histogram is drawn on the plot.

The order in which the variables are drawn is essential to see the clusters. The axes can be dragged to change their position. A zoom is also available. The logarithm scale is also available by right clicking on the axis.

Function documentation

 Default constructor.
TParallelCoordVar(Double_t* val, const char* title, Int_t id, TParallelCoord* gram)
 Normal constructor. By default, the title and the name are the expression given to TTree::Draw. The name
