(41) Legend with tables

In this example we demonstrate how one can use the tool legend to typeset a table within a legend. It also shows how one would set up variable-width columns and fill the cells with a background color.

#!/usr/bin/env bash
#               GMT EXAMPLE 41
#
# Purpose:      Illustrate typesetting of legend with table
# GMT modules:  set, coast, legend, plot, makecpt
#
gmt begin ex41
	gmt set FONT_ANNOT_PRIMARY 12p,Helvetica FONT_LABEL 12p,Helvetica
	gmt makecpt -Cred,orange,yellow,green,bisque,cyan,magenta,white,gray -T1/10/1 -N
