Description

If I plot a filled contour plot overlayed by unfilled contours on a reduced set of levels the map is cropped around the non-filled contours. This seems to be a change between Cartopy 0.18 and 0.19. Is it intentional? I can’t see anything obvious in the whatsnew to explain it.

Code to reproduce

Adapted from some gallery examples…

import cartopy.crs as ccrs
import matplotlib.pyplot as plt
import numpy as np


def sample_data(shape=(73, 145)):
    """Return ``lons``, ``lats`` and ``data`` of some fake data."""
    nlats, nlons = shape
    lats = np.linspace(-np.pi / 2, np.pi / 2, nlats)
    lons = np.linspace(0, 2 * np.pi, nlons)
    lons_2d, lats_2d = np.meshgrid(lons, lats)
    wave = 0.75 * (np.sin(2 * lats_2d) ** 8) * np.cos(4 * lons_2d)
    mean = 0.5 * np.cos(2 * lats_2d) * ((np.sin(2 * lats_2d)) ** 2 + 2)

    lats = np.rad2deg(lats)
    lons = np.rad2deg(lons)
    data = wave + mean

    return lons, lats, data

ax = plt.subplot(111, projection=ccrs.PlateCarree())

lons, lats, data = sample_data()

filled_c = ax.contourf(lons, lats, data, transform=ccrs.PlateCarree())

ax.contour(lons, lats, data,
           levels=filled_c.levels[1:-1],    # Note subset of levels
           colors=['black'],
           transform=ccrs.PlateCarree())

ax.coastlines()

plt.show()

With Cartopy 0.18, we get the whole map:

cartopy_crop_old

With Cartopy 0.19.0.post1 the map gets cropped around the black contours:

cartopy_crop_new

Operating system

RHEL7.9

Cartopy version

0.19.0.post1 (comparing with 0.18)

Conda environments

The python3.8 environments were generated with conda lock files, and the difference between the lock files is show here.
