[ferret_users] plot data at maximum depth

[Joerg Franke <joerg.franke@xxxxxxxxxxxxxxxxxxxx>]

Hi,

is there an easy way to plot data for the bottom of the ocean, always
the greatest depth, were data is available. Maybe something similar to
z=@max which is searching for the depth of the max value but the other
way around: the value at the maximum depth.

Thanks for any help
