Frames, ticks, titles, and labels¶
Setting the style of the map frames, ticks, etc, is handled by the frame
argument
that all plotting methods of pygmt.Figure
.
import pygmt
Plot frame¶
By default, PyGMT does not add a frame to your plot. For example, we can plot the coastlines of the world with a Mercator projection:
fig = pygmt.Figure()
fig.coast(shorelines="1/0.5p", region=[-180, 180, -60, 60], projection="M10i")
fig.show()
Out:
<IPython.core.display.Image object>
To add the default GMT frame to the plot, use frame="f"
in
pygmt.Figure.basemap
or any other plotting module:
fig = pygmt.Figure()
fig.coast(shorelines="1/0.5p", region=[-180, 180, -60, 60], projection="M10i")
fig.basemap(frame="f")
fig.show()
Out:
<IPython.core.display.Image object>
Ticks and grid lines¶
The automatic frame (frame=True
or frame="a"
) sets the default GMT style frame
and automatically determines tick labels from the plot region.
fig = pygmt.Figure()
fig.coast(shorelines="1/0.5p", region=[-180, 180, -60, 60], projection="M10i")
fig.basemap(frame="a")
fig.show()
Out:
<IPython.core.display.Image object>
Add automatic grid lines to the plot by adding a g
to frame
:
fig = pygmt.Figure()
fig.coast(shorelines="1/0.5p", region=[-180, 180, -60, 60], projection="M10i")
fig.basemap(frame="ag")
fig.show()
Out:
<IPython.core.display.Image object>
