Political boundaries
The borders
parameter of pygmt.Figure.coast
specifies levels of
political boundaries to plot and the pen used to draw them. Choose from the
list of boundaries below:
1 = National boundaries
2 = State boundaries within the Americas
3 = Marine boundaries
a = All boundaries (1-3)
For example, to draw national boundaries with a line thickness of 1p and black
line color use borders="1/1p,black"
. You can draw multiple boundaries by
passing in a list to borders
.

fig.basemap(region=[-150, -30, -60, 60], projection="I-90/15c", frame="afg")
# Plot each level of the boundaries dataset with a different color.
fig.coast(borders=["1/0.5p,black", "2/0.5p,red", "3/0.5p,blue"], land="gray")
