default_transform

default_transform(self, func, *args, transform=None, **kwargs)

Wraps plot, scatter, contour, contourf, pcolor, pcolormesh, quiver, streamplot, barbs, tripcolor, tricontour, and tricontourf for GeoAxes.

With the default GeoAxes API, you need to pass transform=cartopy.crs.PlateCarree() if your data coordinates are longitude and latitude instead of map projection coordinates. Now, this is the default.
