class TPolyMarker: public TObject, public TAttMarker


  a PolyMarker is defined by an array on N points in a 2-D space.
 At each point x[i], y[i] a marker is drawn.
 Marker attributes are managed by TAttMarker.
 See TMarker for the list of possible marker types.

~TPolyMarker()
 Desctructor.
TPolyMarker(const TPolyMarker& polymarker)
 Copy constructor.
void Copy(TObject& polymarker) const
Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Compute distance from point px,py to a polymarker.

  Compute the closest distance of approach from point px,py to each point
  of the polymarker.
  Returns when the distance found is below DistanceMaximum.
  The distance is computed in pixels units.
void Draw(Option_t* option = "")

  This member function must be implemented to realize the action
  corresponding to the mouse click on the object in the window
void ls(Option_t* option = "") const
 ls.
Int_t Merge(TCollection* list)
 Merge polymarkers in the collection in this polymarker.
void Paint(Option_t* option = "")
 Paint.

 Paint polymarker.
void Print(Option_t* option = "") const
 Print polymarker.
void SavePrimitive(ostream& out, Option_t* option = "")
 Save primitive as a C++ statement(s) on output stream out.
Int_t SetNextPoint(Double_t x, Double_t y)
 Set point following LastPoint to x, y.
 Returns index of the point (new last point).
void SetPoint(Int_t point, Double_t x, Double_t y)
 Set point number n.
 if n is greater than the current size, the arrays are automatically
 extended
