CurveAdd

Create and add a new curve to the chart.

This version uses the Y coordinate (a curve color is set automatically)

CCurve* CurveAdd(
   const double     &y[],          // Y coordinates
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name
   )

Note

Y array indices are used as X coordinates for the curve.

This version uses the X and Y coordinates (a curve color is set automatically)

CCurve*  CurveAdd(
   const double     &x[],          // X coordinates
   const double     &y[],          // Y coordinates
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name
   )

The version for working with CPoint2D dots (curve color is set automatically)

CCurve*  CurveAdd(
   const CPoint2D   &points[],     // dot coordinates
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name
   )

Version for working with the pointer to the CurveFunction function (curve color is set automatically)

CCurve*  CurveAdd(
   CurveFunction    function,      // pointer to the function
   const double     from,          // initial value of the argument
   const double     to,            // final value of the argument
   const double     step,          // increment by the argument
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name
   )

Version for working by Y coordinate (a curve color is set by a user)

CCurve*  CurveAdd(
   const double     &y[],          // Y coordinates
   const uint       clr,           // curve color
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name
   )

CCurve*  CurveAdd(
   const double     &x[],          // X coordinates
   const double     &y[],          // Y coordinates
   const uint       clr,           // curve color
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name

CCurve*  CurveAdd(
   const CPoint2D   &points[],     // dot coordinates
   const uint       clr,           // curve color
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name
   )

Version for working with the pointer to the CurveFunction function (curve color is set by a user)

CCurve*  CurveAdd(
   CurveFunction    function,      // pointer to the function
   const double     from,          // initial value of the argument
   const double     to,            // final value of the argument
   const double     step,          // increment by the argument
   const uint       clr,           // curve color
   ENUM_CURVE_TYPE  type,          // curve type
   const string     name=NULL      // curve name
   )

Parameters
