Fw: Isentropic Surface

FERETTERS:
   HELLO:     

     I need to plot my variable as a function of potential temperature in
the vertical.  This is typically done by finding a certain temperature
say 340 K by
interpolating between pressure levels and then plotting the variable
along the 340 K surface.  
Is there a function that will do this in ferret?  I need to have a
vertical coordinate that is 
potential temp and not pressure but when i plot my variable it
automatically plots in 
pressure.  I am aware of @LOC, but am not sure of the mechanics because
when i tried this 
it wasn't working correctly.  Any help is greatly appreciated.  I hope i
didn't confuse you with 
this explanation.
