Multi-parameter symbolsΒΆ
The pygmt.Figure.plot
method can plot individual multi-parameter symbols by passing
the corresponding shortcuts listed below to the style
argument. Additionally, we must define
the required parameters in a 2d list or numpy array ([[parameters]]
for a single symbol
or [[parameters_1],[parameters_2],[parameters_i]]
for several ones) or use an
appropriately formatted input file and pass it to data
.
The following symbols are available:
e: ellipse,
[[lon, lat, direction, major_axis, minor_axis]]
j: rotated rectangle,
[[lon, lat, direction, width, height]]
r: rectangle,
[[lon, lat, width, height]]
R: rounded rectangle,
[[lon, lat, width, height, radius]]
w: pie wedge,
[[lon, lat, radius, startdir, stopdir]]
, the last two arguments are directions given in degrees counter-clockwise from horizontal
Upper-case versions E, J, and W are similar to e, j and w but expect geographic azimuths and distances.
For more advanced options, see the full option list at https://docs.generic-mapping-tools.org/latest/plot.html.
