python 画经纬度的函数drawparallel

我想知道里面的label是怎么用的?这里的【1,1,0,1】是什么意思

m.drawparallels(np.arange(24,41,0.05),labels=[1,1,0,1])

    labels = [left,right,top,bottom],左右上下

    labels=[1,1,0,1]即labels=[true,true,false,true]
    即经纬度标签标识地图位置,在地图的左右上下进行标识

    实例代码是说在地图左右和下方标识纬度label信息

    以下是 Jeffrey Whitaker的源码:

    from mpl_toolkits.basemap import Basemap
    import matplotlib.pyplot as plt
    import numpy as np
    # setup Lambert Conformal basemap.
    m = Basemap(width=12000000,height=9000000,projection='lcc',
                resolution='c',lat_1=45.,lat_2=55,lat_0=50,lon_0=-107.)
    # draw coastlines.
    m.drawcoastlines()
    # draw a boundary around the map, fill the background.
    # this background will end up being the ocean color, since
    # the continents will be drawn on top.
    m.drawmapboundary(fill_color='aqua')
    # fill continents, set lake color same as ocean color.
    m.fillcontinents(color='coral',lake_color='aqua')
    # draw parallels and meridians.
    # label parallels on right and top
    # meridians on bottom and left
    parallels = np.arange(0.,81,10.)
    # labels = [left,right,top,bottom]
    m.drawparallels(parallels,labels=[False,True,True,False])
    meridians = np.arange(10.,351.,20.)
    m.drawmeridians(meridians,labels=[True,False,False,True])
    plt.show()
