Basemap m.scatter不允许地图上的点出现并保留填充大陆的颜色。

Question

我有这段Python代码，当我运行它时，点没有出现在我的地图上。

m = Basemap(projection='tmerc',
            llcrnrlon=-10.56,
            llcrnrlat=51.39,
            urcrnrlon=-5.34,
            urcrnrlat=55.43,
            resolution='h',
            epsg=29902)

# Fill the globe with blue color
m.drawmapboundary(fill_color='aqua')

# Draw country boundaries
m.drawcountries()

# Fill the continents with the land color
m.fillcontinents(color='coral', lake_color='aqua')

m.drawcoastlines()

lons = [-7.637558, -5.926437, -6.266155]
lats = [54.350155, 54.607868, 53.350140]

x, y = m(lons, lats)

m.scatter(x, y, marker='D', color='m')

plt.show()

当我运行它时，点没有出现在我的地图上。如果我添加 zorder=0 到 fillcontinents 他们确实出现了，但整个地图是 aqua 颜色。如果我没有 zorder=0 而我用 m.plot 而不是 m.scatter 点被绘制，但线出现在他们之间whic我不想要。

我怎样才能让点在它们之间出现，但又能保留 fillcontinents 颜色？

可能的解决方案

我补充道 zorder=2 到 m.scatter. 这是最Pythonic的方法吗？

m = Basemap(projection='tmerc',
            llcrnrlon=-10.56,
            llcrnrlat=51.39,
            urcrnrlon=-5.34,
            urcrnrlat=55.43,
            resolution='h',
            epsg=29902)

# Fill the globe with blue color
m.drawmapboundary(fill_color='aqua')

# Draw country boundaries
m.drawcountries()

# Fill the continents with the land color
m.fillcontinents(color='coral', lake_color='aqua')

m.drawcoastlines()

lons = [-7.637558, -5.926437, -6.266155]
lats = [54.350155, 54.607868, 53.350140]

x, y = m(lons, lats)

m.scatter(x, y, marker='D', color='m', zorder=2)

plt.show()

Answer 1

我添加了 zorder=2 到 m.scatter. 这是最Pythonic的方法吗？

m = Basemap(projection='tmerc',
            llcrnrlon=-10.56,
            llcrnrlat=51.39,
            urcrnrlon=-5.34,
            urcrnrlat=55.43,
            resolution='h',
            epsg=29902)

# Fill the globe with blue color
m.drawmapboundary(fill_color='aqua')

# Draw country boundaries
m.drawcountries()

# Fill the continents with the land color
m.fillcontinents(color='coral', lake_color='aqua')

m.drawcoastlines()

lons = [-7.637558, -5.926437, -6.266155]
lats = [54.350155, 54.607868, 53.350140]

x, y = m(lons, lats)

m.scatter(x, y, marker='D', color='m', zorder=2)

plt.show()
