Re: [ferret_users] Adding reference lines


I am not sure I understand what you want to do. But if you just want to add a line on your plot, you should use the function "plot/vs/..." such as:

plot/vs/over {32,32},{0,28}

This should add a line on your plot at x=32, and between y=0 and y=28.

Hello dear Ferret community,


I have been trying to add some reference lines to my plots and have come up against a wall.


I have some plots of SST as a function of Latitude (90°S to 90°N, which is grid cells 0:112, see below) and would like to add a reference line at 40°S (grid cell 32) and 40°N (grid cell 81). However, after looking through the ferret manuals I haven’t been able to find any information about adding reference lines.


I hope I am not annoying anyone with this simple problem.


Something like this!

Parts of the Ocean are predicted to lose oxygen in the coming century. But why?

Looking into the past, how does oxygen in the ocean change across climate transitions?
