Hello GMT family,
I want to draw three auto-tagged maps in a 2x2 subplot, such that the first map spans across the upper half of the figure. So, my figure should be something like an up-down flip of the one on the right. Can someone kindly help me out? Thanks very much.
This is the script I used:
gmt begin QQQ png
gmt subplot begin 2x2 -A+JTL+o-0.15i/0.07i -Fs6.2i/3i -M0i/0.3i -Rd -JH13.5c -Bxa60 -Bya0
gmt subplot set 0:1 -A"a)"
gmt coast -A3000 -Gpeachpuff4 -Dh -Wthinnest -Slightblue
gmt subplot set 2 -A"b)"
gmt coast -A3000 -Ggray60 -Dh -Wthinnest -Sazure1
gmt subplot set 3 -A"c)"
gmt coast -A3000 -Gdarkbrown -Dh -Wthinnest -Sgray72
gmt subplot end
gmt end show
The example plots Cartesian frames but it also works for geographic maps. The key point in this example is that you need to call subplot begin twice because GMT doesn’t support nested subplot yet.
