Cartopy seems like a great tool for Geoscience, but it appears to lack a method for plotting vector data on a map together with their error ellipses. Is there a straightforward way to add error ellipses centered on the tips of vector data?
回答1:
Cartopy inherits all its vector plotting functionality from matplotlib. Cartopy provides a way to project the vectors, but they are drawn by matplotlib. I haven't heard of a feature you describe in matplotlib, so I'm afraid the answer is probably no.
