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()

 Default constructor.

~TParallelCoordVar()

Destructor.

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
 can be changed by the user (the label on the plot) but not the title.

void AddRange(TParallelCoordRange* range)

 Add a range to the current selection on the axis.

void DeleteVariable()

 Delete variables.

Int_t DistancetoPrimitive(Int_t px, Int_t py)

 Computes the distance from the axis.

void Draw(Option_t* option = "")

 Draw the axis.

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 ExecuteEvent(Int_t entry, Int_t px, Int_t py)

 Execute the corresponding entry.

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.

TH1F* GetHistogram()

 Create or recreate the histogram.

void GetMinMaxMean()

Get mean, min and max of thos variable

char* GetObjectInfo(Int_t px, Int_t py) const

 Returns info about this axis.

void GetQuantiles()

 Get the box plot values (quantiles).

Double_t GetValuefromXY(Double_t x, Double_t y)

 Get the value corresponding to the posiiton.

void GetXYfromValue(Double_t value, Double_t& x, Double_t& y)

 Get a position corresponding to the value on the axis.

void Init()

 Initialise the TParallelVar variables.

void Paint(Option_t* option = "")

 Paint the axis.

void PaintBoxPlot()

 Paint the boxes in the case of a candle chart.

void PaintHistogram()

 Paint the histogram on the axis.

void PaintLabels()

 Paint the axis labels and titles.

void Print(Option_t* option = "") const

 Print the axis main datas.

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 SetBoxPlot(Bool_t box)

 Set the axis to display a candle.

void SetHistogramBinning(Int_t n = 100)

 Set the histogram binning.

void SetHistogramHeight(Double_t h = 0)

 Set the height of the bar histogram.

void SetCurrentMin(Double_t min)

 Set the current minimum of the axis.

void SetCurrentMax(Double_t max)

 Set the current maximum of the axis.

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 SetLogScale(Bool_t log)

 Set the axis in logscale.

void SetValues(Long64_t length, Double_t* val)

 Set the variable values.

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.
