I said y = x^4 ( or x = y^1/4 ) so that the height of water increases linearly with time. That's correct, but in the program I used x = sqrt (y), that is, y = x^2.

I've edited my version upside.
I think using complex numbers to plot do the thing far more easy with CONJ and NEG features and PDIM scale.
