Hi, all

By google, I understand the Excel can do such job.

But I just wonder whether GMT can plot such figure.

Dose someone have interest for plotting it using GMT if possible?

My data looks like:

Thanks.
But how to define the color by data?

4

You want a choropleth map, which is not a trivial thing to do in GMT. Unless you use the Julia wrapper.

5

Looks great! I love your work.
Seems I should try to learn Julia GMT.

6

Maybe a nice addition to coast would be to add an -l option, e.g. to allow painted countries to be in the legend.

7

for loop ?

cat << 'EOF' > cntries.txt
FR	blue
US	red
AU	brown
BR	hotpink
IN	orange
SD	antiquewhite2
EOF

gmt begin test png
	gmt coast -Rg -JQ0/0/10c -Wfaint -B -Ggray -N1
	for i in {1..14};
	do
	a=$(awk -v var=$i 'NR==var {print $1}' cntries.txt)
	b=$(awk -v var=$i 'NR==var {print $2}' cntries.txt)
	gmt coast -E${a}+g${b}
	done

gmt end show

rm -f cntries.txt
