Subject: Correctly plot the tank end pressure if it was set manually
X-Git-Url: http://git.tdb.fi/?p=ext%2Fsubsurface.git;a=commitdiff_plain;h=abdee5b1b8a97c641bca9bc2ebac9555c3e2ea54

Correctly plot the tank end pressure if it was set manually

While printing the last pressure in the calculated sequence may seem more
logical, given that the discrete series will create some amount of error
this simply looks wrong. Instead we pick the end pressure that was
manually set.
