{
// Interpolate points in this graph at x using a TSpline
// -if spline==0 and option="" a linear interpolation between the two points
// close to x is computed. If x is outside the graph range, a linear
// extrapolation is computed.
// -if spline==0 and option="S" a TSpline3 object is created using this graph
// and the interpolated value from the spline is returned.
// the internally created spline is deleted on return.
// -if spline is specified, it is used to return the interpolated value.
