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.

Unlike traditional GMT figures, no figure file is generated until you call pygmt.Figure.savefig or pygmt.Figure.psconvert.

Examples

>>> fig = Figure()
>>> fig.basemap(region=[0, 360, -90, 90], projection='W7i', frame=True)
>>> fig.savefig("my-figure.png")
>>> # Make sure the figure file is generated and clean it up
>>> import os
>>> os.path.exists('my-figure.png')
True
>>> os.remove('my-figure.png')

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

>>> fig = Figure()
>>> fig.basemap(region='JP', projection="M3i", frame=True)
>>> # The fig.region attribute shows the WESN bounding box for the figure
>>> print(', '.join('{:.2f}'.format(i)  for i in fig.region))
122.94, 145.82, 20.53, 45.52

Attributes:

region

The geographic WESN bounding box for the current figure.
