;Spline( <List of Points> )
:Creates a cubic [[w:Spline_(mathematics)|spline]] through all points.
;Spline( <List of Points>, <Order ≥ 3> )
:Creates a spline with given order through all points.
;Spline( <List of Points>, <Order ≥ 3>, <Weight Function )
:Creates a spline with given order through all points. The weight function says what should be the difference of t values for point P<sub>i</sub> and P<sub>i+1</sub> given their difference P<sub>i+1</sub>-P<sub>i</sub>=(x,y). To get the spline you expect from "function" algorithm you should use <code>abs(x)+0*y</code>, to get the GeoGebra's default spline you can use <code>sqrt(x^2+y^2)</code>. 
:{{Note|The choice of default makes the result behave nicely when transformed, making sure that <code>Rotate(Spline(list), a)</code> gives the same as <code>Spline(rotate(list, a))</code>.}}
