Function documentation

TGLAxis(const TGLAxis& )
 Constructor.
void Init()
 Default initialization.
~TGLAxis()
 Destructor.
void PaintGLAxis(const Double_t* p1, const Double_t* p2, Double_t wmin, Double_t wmax, Int_t ndiv, Option_t* opt = "")
 Paint GL Axis.

 p1, p2     : Axis position in the 3D space.
 wmin, wmax : Minimum and maximum values along the axis. wmin < wmax.
 ndiv       : Number of axis divisions. It is an integer in the form
              "ttsspp" where "tt" is the number of tertiary divisions,
              "ss" is the number of secondary divisions and "pp" the
              number of primary divisions.
 opt        : Options.
              "N" - By default the number of divisions is optimized to
                    get a nice labeling. When option "N" is given, the
                    number of divisions is not optimized.
void PaintGLAxisBody()
 Paint horizontal axis body at position (0,0,0)
void PaintGLAxisTickMarks()
 Paint axis tick marks.
void PaintGLAxisLabels()
 Paint axis labels on the main tick marks.
void TicksPositions(Option_t* opt = "")
 Compute ticks positions.
void TicksPositionsNoOpt()
 Compute ticks positions. Linear and not optimized.
void TicksPositionsOpt()
 Compute ticks positions. Linear and optimized.
void DoLabels()
 Do labels.
void SetLabelsAngles(Double_t a1, Double_t a2, Double_t a3)
 Set labels' angles.
TGLAxis(const TGLAxis& )
void SetTickMarksLength(Double_t length)
{fTickMarksLength = length;}
void SetTickMarksOrientation(Int_t tmo)
{fTickMarksOrientation = tmo;}
void SetLabelsOffset(Double_t offset)
{fLabelsOffset = offset;}
void SetLabelsSize(Double_t size)
{fLabelsSize = size;}
void SetGridLength(Double_t grid)
{fGridLength = grid;}
