TXYcurveObj

TXYcurveObj
Type-access		Command	Description
Implements the following properties/methods as in TLoadShapeObj and TLineObj: InitPropertyValues DumpProperties GetPropertyValue Set_NumPoints SaveWrite NumPoints
Property-private	InterpolatePoints			Returns a point after interpolating the given coordinates.
Property-private	Get_YValue			Get Y Value by index.
Property-private	Get_XValue			Get X Value corresponding to point index.
Method-private	Set_XValue			Sets X Value corresponding to point index.
Method-private	Set_YValue			Sets Y Value corresponding to point index.
Property-private	Get_X			Get X present value.
Property-private	Get_Y			Get Y present value.
Method-private	Set_X			Sets present X value.
Method-private	Set_Y			Sets present Y value.
Property-public	GetYValue			Get Y value at specified X Value.
Property-public	GetXValue			Get X value at specified Y Value.
Property-public	GetCoefficients			This function returns the coefficients of the line interpolated line for the given X (a*X + b). If no points exist in the curve (or just a single point), the result is (a = 0, b = 0). If Xvalue is outside the range of defined X values, the curve is extrapolated from the Ends (a = 0, b = extrapolated value).
Property-public	XValue_pt			PA Get_XValue and Set_XValue.
Property-public	YValue_pt			PA Get_YValue and Set_YValue.
Property-public	X			PA Get_X and Set_X.
Property-public	Y			PA Get_Y and Set_Y.
