Re: [ferret_users] plot/vs and axes

I am not sure If you want shade to be after plot  command for some reason,  else it should work as below

let xpnts = {20,180}
set var/units=degrees_east xpnts
let ypnts = {-80,80}
set var/units=degrees_north ypnts

set data coads_climatology

shade/l=1  SST     
plot/lines/thick=3/vs /ov xpnts,ypnts

Ferret users,

I'm wondering how to keep a line plotted by a PLOT/VS
command in subsequent overlays:

1. Plot the line using PLOT/VS .
2. "SHADE/OV var" would erase the line.

I notice that the SHADE/OV command doesn't honor the
coordinates set by PLOT/VS .

A complete example is attached.

I don't want the SHADE command to erase the line.
I know a workaround is to SHADE, PLOT/VS, and SHADE,
but if possible, I'd like to avoid the redundant
first SHADE .

Regards,
Ryo

let xpnts = {20,180}
set var/units=degrees_east xpnts
let ypnts = {-80,80}
set var/units=degrees_north ypnts

set data coads_climatology

! In the following sequence, the SHADE
! command erases the line.
plot/lines/thick=3/vs xpnts,ypnts
shade/l=1/ov SST     !! --> Erases the lines

! The following sequence plots the line
! over the shading.
shade/l=1 SST
plot/lines/thick=3/vs/ov xpnts,ypnts
