Re: [ferret_users] new beginner to plot bathymetry file in ASCII

["William S. Kessler" <william.s.kessler@xxxxxxxx>]

You need to specify a format, number of columns (and possibly the  
order of reading).

Also you need to explicitly define the grid called bathymetry, not  
just the axes

define grid/x=longitude/y=latitude bathymetry
file/format=(186f14.3)/var=ps/grid=bathymetry/columns=186  
bathy_input.btm

That should work if each row contains all the 186 x-values for a  
single y, and moves down one row for each y. Otherwise, adjust format  
and columns. If the order of x and y are switched, use the /order=yx  
qualifier on FILE.
