pygmt.Figure

class pygmt.Figure

A GMT figure to handle all plotting.

Use the plotting methods of this class to add elements to the figure. You can preview the figure using pygmt.Figure.show and save the figure to a file using pygmt.Figure.savefig.

Examples

>>> import pygmt
>>> fig = pygmt.Figure()
>>> fig.basemap(region=[0, 360, -90, 90], projection="W15c", frame=True)
>>> fig.savefig("my-figure.png")
>>> # Make sure the figure file is generated and clean it up
>>> from pathlib import Path
>>> assert Path("my-figure.png").exists()
>>> Path("my-figure.png").unlink()

The plot region can be specified through ISO country codes (for example, "JP" for Japan):

>>> import pygmt
>>> fig = pygmt.Figure()
>>> fig.basemap(region="JP", projection="M7c", frame=True)
>>> # The fig.region attribute shows the WESN bounding box for the figure
>>> print(", ".join(f"{i:.2f}" for i in fig.region))
122.94, 145.82, 20.53, 45.52

Attributes

property Figure.region: ndarray

The geographic WESN bounding box for the current figure.
