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.
