Dear List,

I'm trying to develop a custom symbol to annotate every 10° latitude and longitude with their respective values. The GMT Docs state: "You can embed %X or %Y to add the current longitude (or x) and latitude (or y) in your label string." (25.2.4. "Text substitution")

I only got the string "%Y" in the plotted symbol. See screenshot at http://kristofkoch.de/gmt/text_string_subst.png [1]


I tried the following (bash script):

cat > lat_label.def << END
0a R
0.1 -0.1 7p \%Y l+jTL -W- -Gblack
END


Maybe I didn't understand the documentation concerning the expansion of special codes. I'd be grateful if anyone can point out the correct usage of "%Y".

Regards,
Kristof Koch
