Re: [ferret_users] Y-AXIS SCALE

[Paul Young <Paul.J.Young@xxxxxxxx>]

Hi Steeven,

My guess is that the netcdf file that you are reading in doesn't have  
the coordinate values associated with the z axis (0-600m), or that  
ferret isn't managing to read them in for some reason. One solution is  
to regrid the z axis,

define axis/z=0:600:10/units=meters/depth new_z				!Define new z axis;  
bottom of graph is 600m level
let new_d20 = d20[gz=new_z@asn]							!Define new var which is old var  
on new axis

plot/vlimits=600:0:10/set new_d20
ppl ylab "Depth / m"											!Add y-axis title
ppl plot

You might want to check my syntax in the "regridding" part of the  
ferret documentation, but I think this should work.

Cheers,

Paul
