Logo

The pygmt.Figure.logo method allows to place the GMT logo on a map.

import pygmt

fig = pygmt.Figure()
fig.basemap(region=[0, 10, 0, 2], projection="X6c", frame=True)

# Add the GMT logo in the Top Right (TR) corner of the current map,
# scaled up to be 3 cm wide and offset by 0.3 cm in x direction
# and 0.6 cm in y direction.
fig.logo(position="jTR+o0.3c/0.6c+w3c")

fig.show()
