plotting a time series over a hovmuller plot

[Hein Zelle <zelle@xxxxxxx>]

Dear Ferret users,

I have a problem I am not sure how to solve. What I want to do is the
following: I have 2 variables, SST and ZEROPOINT. SST is defined on
the x axis (y = 0n) and in time, and I make a hovmuller plot using
fill (lon-time). ZEROPOINT is a variable only defined in time, with
the value indicating a longitudinal position where the wind field is
zero. I can plot this line, resulting in a t-lon plot (t along the x
axis). What I want is to plot this line as a lon-t plot (axes swapped)
and overlay it on top of my SST plot (with the axes matching, of
course).

Does anyone have a clue how I can do this? I have a solution in the
form of a contour plot which approximates the line plot, but this is
not really what I want. If anyone knows a way to plot this one
dimensional variable directly on top of my hovmuller plot, I would be
much obliged.
