Méthodes publiques

Méthode	Description
Clone ( ) : object	Deep Copy of the LogAxis.
LogAxis ( ) : System	Default constructor.
LogAxis ( Axis a ) : System	Copy Constructor
LogAxis ( double worldMin, double worldMax ) : System	Constructor
PhysicalToWorld ( PointF p, PointF physicalMin, PointF physicalMax, bool clip ) : double	Return the world coordinate of the projection of the point p onto the axis.
WorldToPhysical ( double coord, PointF physicalMin, PointF physicalMax, bool clip ) : PointF	World to physical coordinate transform. TODO: make Reversed property work for this.

Méthode	Description
DoClone ( LogAxis b, LogAxis a ) : void	Helper method for Clone (actual implementation)

CalcGrids ( double dLenAxis, int nNumDivisions, double &dDivisionInterval ) : void
DetermineNumberSmallTicks ( double bigTickDist ) : int	Determines the number of small ticks between two large ticks.
DetermineTickSpacing ( ) : double	Determines the tick spacing.
Init ( ) : void
WorldTickPositions_FirstPass ( Point physicalMin, Point physicalMax, ArrayList &largeTickPositions, ArrayList &smallTickPositions ) : void	Determines the positions, in world coordinates, of the log spaced large ticks.
WorldTickPositions_SecondPass ( Point physicalMin, Point physicalMax, ArrayList largeTickPositions, ArrayList &smallTickPositions ) : void	Determines the positions, in world coordinates, of the small ticks if they have not already been generated.

Deep Copy of the LogAxis.

public LogAxis ( double worldMin, double worldMax ) : System
worldMin	double	Minimum World value for the axis.
worldMax	double	Maximum World value for the axis.
Résultat	System

Return the world coordinate of the projection of the point p onto the axis.

public PhysicalToWorld ( PointF p, PointF physicalMin, PointF physicalMax, bool clip ) : double
p	System.Drawing.PointF	The point to project onto the axis
physicalMin	System.Drawing.PointF	The physical position corresponding to the world minimum of the axis.
physicalMax	System.Drawing.PointF	The physical position corresponding to the world maximum of the axis.
clip	bool	If true, the world value will be clipped to WorldMin or WorldMax as appropriate if it lies outside this range.
Résultat	double

World to physical coordinate transform.

TODO: make Reversed property work for this.

public WorldToPhysical ( double coord, PointF physicalMin, PointF physicalMax, bool clip ) : PointF
coord	double	The coordinate value to transform.
physicalMin	System.Drawing.PointF	The physical position corresponding to the world minimum of the axis.
physicalMax	System.Drawing.PointF	The physical position corresponding to the world maximum of the axis.
clip	bool	if false, then physical value may extend outside worldMin / worldMax. If true, the physical value returned will be clipped to physicalMin or physicalMax if it lies outside this range.
Résultat	System.Drawing.PointF
