Re: [ferret_users] symbols shown as a legend

Hi Yangxing -

See the many symbol fonts available at:

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/appendix- b-pplus-guide/PPLUS-COMMAND-FILES#AppendixB_Embedded%20strings

and the sublinks on that page to "Tables showing the character fonts" and "Tables showing the symbol fonts".

You might also check out several legend scripts in the user group e- mails. See, for example, the script attached to

http://www.pmel.noaa.gov/maillists/tmap/ferret_users/fu_2006/ msg00804.html

Dear ferreters,

I am not a skilled ferret user and have a questions to ask you.

If I want to make a scatter plot for several variables, we usually point out what the symbols stand for. For example,

       plot/vlim=-1:4:0.5/hlim=0:20:1/nolab/symbol=2 sst
        plot/vlim=-1:4:0.5/hlim=0:20:1/nolab/symbol=20 v

We know that symbol =2 is X (cross), and symbol = 20 is hollow triangle. The problem is how we can denote X is for sst and the triangle is for v, something like legend?

      I am not sure if we can use the command like
label/nouser `($ppl$xlen)*(0.03)`,`($ppl$ylen)*0.92`,0,0,0.12 "@CR X: sst" label/nouser `($ppl$xlen)*(0.03)`,`($ppl$ylen)*0.92`, 0,0,0.12 "@CR ?: v"

If it is OK, how can we represent the triangle and other symbols within " "?
