Wiggle along tracksΒΆ

The pygmt.Figure.wiggle method can plot z = f(x,y) anomalies along tracks. x, y, z can be specified as 1d arrays or within a specified file. The scale parameter can be used to set the scale of the anomaly in data/distance units. The positive and/or negative areas can be filled with color by setting the color parameter.
