Re: [ferret_users] contour actual code

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Patricia,
The entire source code for Ferret is available from the Ferret Downloads 
pages,

http://ferret.pmel.noaa.gov/Ferret/downloads/downloading_ferret

The contouring routine is in old (but good!) Fortran.  Once you untar 
the source code, it can be found in the file,
FERRET/ppl/plotlib/contur.F

It does not only the contouring, drawing lines as it goes, but also 
interrupts the lines to make the numeric contour labels.  A bit of the 
origin of the code is discussed here,
