Hi Billy,

Thank you for your input,

Ferret is making an appropriate choice to center the limits on the equator. Most of the time that is what is wanted.

I agree. For the automatic-axis mode, the default choice is the best one.

Specifying an interval of 20 on VLIMITS gets a tick at the southern end:

yes? fill/vlimits=-20:5:20/hli=5:20:5/l=1/k=1 temp   ! blank plot but whatever

Not on my screen, I'm afraid.  What am I doing differently from you?  (I tested this on FERRET v6.82 and v6.94).  Just in case, this is what I did:

yes? set data levitus_climatology

yes? fill/vlimits=-20:5:20/hli=5:20:5/l=1/k=1 temp

 

Then it is a simple matter to draw a tick on the northern end:

yes? ppl window,off;plot/vs/over/nolab/line=1 {5,4.8},{5,5}

Seems like it takes a lot less time to do that than to try to come up with a workaround.

For more than a few ticks, it's pretty easy to use a REPEAT loop to draw ticks and labels manually.

Am I missing something?

The numeric label. I should've been clear. 

In any case, the point is NOT that you can do it manually.  As I said, you can always do it manually.

Manually adjusting the positions and sizes of the tics and numeric labels to match those Ferret plots isn't fun.  If you go the manual way, probably you want to plot all tics and labels manually.  (Because, currently, I have four plots in a single page, I'd have to adjust the sizes to match those on the other plots and other axes.)

Perhaps one can write a generic Ferret script that can replace all tics and labels . . . .

Regards,

Ryo
