Re: [ferret_users] how to fill using ASCII data

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

Hi Wendy,
To do a fill plot with this data, you need to read the data and use it 
to create a grid.  This would be similar to the example in the Users 
Guide in the index under "ASCII data, reading, examples", example 4, 1 
variable, 2 dimensions.  lat and depth are the dimensions.  It's 
probably simplest to just look at the file and create the grid in the 
script, though we could work out how to get Ferret to read the latitude 
column and create the Y axis, and the depth column to create the Z axis.

yes? define axis/y=-8:55:1/units=degrees yax  ! using whatever is the 
correct upper latitude
yes? define axis/z/units=meters/depth zax = {10,25,40,60,100}

yes? define grid/y=yax/z=zax yzgrid

 ! set the command to read but not use the first and third columns
yes? file/var="a,ch1,b"/skip=1/grid=yzgrid  filename.dat

yes? fill ch1
