【问题描述】：

我有这个 Python 代码：

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，这些点不会出现在我的地图上。如果我将zorder=0 添加到fillcontinents，它们确实会出现，但整个地图是aqua 颜色。如果我没有zorder=0 并且我使用m.plot 而不是m.scatter，那么会绘制点，但它们之间会出现我不想要的线。

如何让点自行显示但保留fillcontinents 颜色？

可能的解决方案

我将zorder=2 添加到m.scatter。这是最 Pythonic 的方式吗？

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()
