Hydrostatic pressure along green and orange axes with water surface

[azerbajdzan]

We are interested in pressure along green axis in the first picture and along orange axis in the second picture.
Air pressure is constant everywhere.

For the first case:

under water surface:
p = p_atm + ro.g.h

p_atm = 10⁵ Pa = 10⁵ kg.m^-1.s^-2
ro = 10³ kg.m^-3
g = 10 m.s^-2
h = 1-x

above water surface:
p = p_atm

So we have
for 0 <= x <= 1: p = 100000 + 10000(1-x)
for x>=1: p = 100000

Graph for the first case is in third picture.

How is it for the second case?

Is it like this for the second case? (see picture)
