如何使用python中的Basemap减少我在地图上绘制的地点的点大小?

this is the existing plot

绘图的代码是:

m = Basemap(width=4000000,height=4000000,projection='lcc',
        resolution='c',lat_1=45.,lat_2=55,lat_0=20,lon_0=80.)
m.drawmapboundary(fill_color='aqua')
m.drawcountries()
m.drawcoastlines(linewidth=0.50)
m.fillcontinents(color='green', alpha = 0.6, lake_color='aqua')
for i in range(len(lngtd)):
    lon = lngtd[i]
    lat = lattd[i]
    xpt,ypt = m(lon,lat)
    lonpt, latpt = m(xpt,ypt,inverse=True)
    m.plot(xpt,ypt,'ro')
plt.show()

为将来的访问者添加完整答案。将markersize关键字添加到该行:

m.plot(xpt,ypt,'ro')

制作:

m.plot(xpt,ypt,'ro', ms="2.0")
