I made the following figure where the data is colored based on months-data as can be seen from the colorbar. I create the cpt with this commands:
gmt makecpt -Crainbow -T1/12/1 -F+cJan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec -H > a.cpt
I have to write the abbreviated name of each month. Is there an automatic way to do this? Something like
-F+c"Month" ? Should I request the feature?
