Thanks for that, burnin! Good tip! The correct way to do it would be "Spline Presets" -> "Root" and then "Flip Vertical". That's exactly what is needed to get 1 - sqrt(x) ;-)

oh, missed that :D thanks

looking at it again, there's also a "Custom..." option which asks for formula/function and allows any number of control points ;)
