Syntax

[C/C++:]
void ggAddGraphSpline(int npts, GPOINT *points);

[F90:]
subroutine ggAddGraphSpline(npts, points)

integer, intent(in) :: npts
type(GPOINT), intent(in) :: points(*)

Arguments

npts
The number of points to be plotted

points
Array of dimension npts, giving the X and Y axis values of the points to be defined on the graph

Description

The routine ggAddGraphSpline() fits a cubic spline through the points defined in array points, with respect to the current axes as set up by the last axis definition calls. The points are not marked on the graph. If axes have not been defined, the points will be read and plotted according to the default values for axis positioning and scaling. This could result in points being outside the available drawing area or current window.

The end conditions may be set by using the routines ggSetCurveStartConds() and/or ggSetCurveEndConds().
