class TParallelCoordVar: public TNamed, public TAttLine, public TAttFill
Axes:
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
TParallelCoordVar(Double_t* val, const char* title, Int_t id, TParallelCoord* gram)
Bool_t Eval(Long64_t evtidx, TParallelCoordSelect* select)
Check if the entry is within the range(s) of "select". Two ranges on a single axis are conjugated as a "or": to be selected, the entry must be in one of the ranges.
void GetEntryXY(Long64_t n, Double_t& x, Double_t& y)
Get the position of the variable on the graph for the n'th entry.
Int_t GetEntryWeight(Long64_t evtidx)
Get the entry weight: The weight of an entry for a given variable is the bin content of the histogram bin the entry is going through.
void GetXYfromValue(Double_t value, Double_t& x, Double_t& y)
Get a position corresponding to the value on the axis.
void SavePrimitive(ostream& out, Option_t* options)
Save the TParallelCoordVar as a macro. Can be used only in the context of TParallelCoord::SavePrimitive (pointer "TParallelCoord* para" is defined in TParallelCoord::SavePrimitive) with the option "pcalled".
void SetCurrentLimits(Double_t min, Double_t max)
Set the limits within which one the entries must be painted.
void SetLiveRangesUpdate(Bool_t on)
If true, the pad is updated while the motion of a dragged range.
void SetX(Double_t x, Bool_t gl)
Set the X position of the axis in the case of a vertical axis. and rotate the axis if it was horizontal.
void SetY(Double_t y, Bool_t gl)
Set the Y position of the axis in the case of a horizontal axis. and rotate the axis if it was vertical.
void AddRange(TParallelCoordRange* range)
