Dear Russ,

sometimes i am also facing the same problem to set the origin at desire LAT, LON but cant able to do so. i hope this problem will be fix in the next version of ferret/Pyferret.

regards, saurabh

Ferret users,

I wonder how to set the origin of the tics.

Currently, I'm struggling to have ticks right at the edges of the axis and there only:

set data levitus_climatology
fill/hlimits=5:20/vlimits=-20:5:25/l=1/k=1 temp

Look at the y axis. I want the labels and tics right at 20S and 5N and there only, but the only tic I get is "0" (equator). I was trying to discover a PPL trick to do this, but . . .

. . . In the meanwhile, I re-discovered the following thread I myself started many years ago:

http://www.pmel.noaa.gov/maillists/tmap/ferret_users/fu_2007/msg00299.html

I guess that means that there is no way to do this, except for manually calling polygon and label commands to draw the short line segments and the text?

If this feature is really missing from Ferret, I wonder if it is worth implementing? I would think the following two features would be very useful:

1) set the origin, interval, and endpoint of tics.

2) set tics and arbitrary labels at arbitrary positions. If I use the gnuplot syntax:

set ytics ("pi" 3.14159, "4pi" 12.5664)
set xtics ("small" 1, "medium" 10, "large" 100)

Best regards,

Ryo
