Hi!
I’m trying to plot longitude and latitude depth sections of seismicity across a map area that uses the Mercator projection. I can use two Cartesian axes for the longitude section, as the distance per degree is constant separation. However, as the distance per degree for the latitude axes changes, the Cartesian axes are not suitable.
Is it possible to set a projection for the geographic axis on the depth section? Below is the code that I’m using.
gmt plot -R0/800/-50d/-30d -JX5c/14d quakes.txt -C -Sc
Thanks!
