I am new for Generic Mapping Tool (GMT), but I would like to work through a few simple examples of generating legends (ie. multiple points or lines plotted on a single figure using psxy). In the following example, I want a set the location of Legend in the southwest (Inside bottom-left of axes).
gmt psbasemap -R-108/-105/31/35 -JM6i -Ba0.5 -K -P> New_Mexico.ps
gmt pscoast -R -J -Df -Gwhite -O -K -P>> New_Mexico.ps
gmt psxy Data1.txt -R -J -Sc0.5c -Gblue -O -K -P >>New_Mexico.ps
gmt psxy Data2.txt -R -J -St0.5c -Gred -O -K -P>>New_Mexico.ps
gmt psxy Data3.txt -R -J -Ss0.5c -Ggreen -O -K -P>>New_Mexico.ps
Good afternoon,
Indeed, the user manual should help you. Personaly, I used a lot GMT during my thesis but i prepared the legends using Adobe Illustrator. You can open the postscript folder with it and customize your figures easily since it is a vectorial format.
All the best,
Yannick
Dear Abd-Elrahim Ruby,
I am also new in GMT, but I have found a good manual "Getting Sterted with GMT: An Introduction to Seismologists" by Matthew R. Agius, you can request a full-text, hope it will help you.
Best regards,
Katerina
Dear Abd-Elrahim Ruby,
you can try to add this command:
gmt pslegend -DJRT+w4.7c/1.4c+o-5.0c/-2c -F+gwhite+p2 -O -J -R > test.ps
S 0.2s s 0.3s green - 0.2i "description of green squares, for example"
S 0.2s s 0.3t red - 0.2i "description of red triangles" and so on....
