python地图散点图_python – Cartopy：使用散点图数据渲染图层的顺序

我试图使用Cartopy在地图上绘制几个点(散点图)的位置(参见下面的代码).当我尝试渲染绘图时,数据点将在LAND层后面呈现.但我想在LAND-layer上绘制我的分散数据……我做错了什么？

Cartopy：ver. 0.12.x,Matplotlib：ver.1.4.2

import matplotlib.pyplot as plt

import cartopy.crs as ccrs

import cartopy.feature as cfeature

ax = plt.axes(projection=ccrs.PlateCarree())

ax.set_extent([125, 150, 35, 63])

ax.stock_img()

ax.add_feature(cfeature.LAND) #If I comment this => all ok, but I need

ax.add_feature(cfeature.LAKES)

ax.add_feature(cfeature.RIVERS)

ax.coastlines()

ax.scatter(yc,xc,transform=ccrs.PlateCarree()) #yc, xc -- lists or numpy arrays

plt.show()
