I have a plot in Cartesian coordinate system, and I would like to add a rotated directional rose to depict North direction, which doesn’t seem to work, see below?
gmt begin test png
gmt basemap -R0/10/0/10 -JX5c/5c -BWSne -Baf
gmt basemap -TdjTL+w1.5c+l,,,N
gmt end
I guess such symbol must be stored some where in GMT, and I was wondering if there is a way to manually add this symbol, rotated, onto the plot?
I see that there is no “North” in Cartesian, but since this is a rotated domain, I would still like to show readers the “North” after the rotation.
Is it possible that we can fetch the GMT rose and put it rotated on the plot? Otherwise, we have to create a rose symbol or drape an external figure as the directional rose?
