Remarks

This is an abstract base class and cannot be instantiated directly. Instead, use one of the derived classes as listed in the following table:

PiecewiseConstantCurve	Represents a curve that is piecewise constant.
PiecewiseLinearCurve	Represents a piecewise linear function.
CubicSpline	Represents a natural or clamped cubic spline curve, a piecewise 3rd degree polynomial with smoothness and continuity properties.

Methods

Clone	Constructs an exact copy of this instance. (Inherited from Curve)
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
FindRoots	Gets the set of X-coordinates where the curve crosses the X-axis. (Inherited from Curve)
GetCurveFitter	Returns a CurveFitter object that can be used to fit the curve to data. (Inherited from Curve)
GetDataPoint	Gets the data point with the specified index.
