Inset

The pygmt.Figure.inset method adds an inset figure inside a larger figure. The method is called using a with statement, and its position, box, offset, and margin parameters are set. Plotting methods called within the with statement are applied to the inset figure.

import pygmt

fig = pygmt.Figure()
# Create the primary figure, setting the region to Madagascar, the land color
# to "brown", the water to "lightblue", the shorelines width to "thin", and
# adding a frame
fig.coast(region="MG+r2", land="brown", water="lightblue", shorelines="thin", frame="a")
# Create an inset, placing it in the Top Left (TL) corner with a width of 3.5 cm and
# x- and y-offsets of 0.2 cm. The margin is set to 0, and the border is "gold" with a
# pen size of 1.5 points.
with fig.inset(position="jTL+w3.5c+o0.2c", margin=0, box="+p1.5p,gold"):
    # Create a figure in the inset using coast. This example uses the azimuthal
    # orthogonal projection centered at 47E, 20S. The land color is set to
    # "gray" and Madagascar is highlighted in "red3".
