That is my problem. The function should be nonlinear. However, we can break
it down to the first 3 or 4 points could be linear and then nonlinear
function. On the later points can we apply sort of spline function or local
polynomials?

I did not succeed to reconstruct the sequence of points,
through which the density curve should go.

 0.23 should be y-coordinate.

Yes

     that is correct!

      Y-coordinate
