Try the Freehand Shape tool (which makes a function)

Salut Camilla!


It seems that you think that there must exist one term/function to describe the line.

This is not correct, because "in the middle area" it is constant 3.3, so there is no differentiable not constant function for the domain [0, 19.76].

So it maybe better to try and think instead of a piecewise function with three or four sections and try to interpolate them.
