python中国地图代码 上色_如何让使用python绘制中国地图并给特定地区上色?_第1张图片

我是准备给14个地区染色,但是能成功上色的只有6个省和直辖市。

请问这是Basemap画地图的bug吗?

在绘制的过程中参考的是

请问这是Basemap画地图的bug吗?

代码如下:

plt.figure(figsize=(16,10))

map = Basemap(llcrnrlon=77, llcrnrlat=14, urcrnrlon=140, urcrnrlat=51,projection='lcc',lat_1=33, lat_2=45, lon_0=100)

map.drawcoastlines()

map.readshapefile('CHN_adm1', 'states', drawbounds=True)

#map.drawcountries()

statenames=[]

for shapedict in map.states_info:

statename = shapedict['NL_NAME_1']

p = statename.split('|')

if len(p) > 1:

s = p[1]

else:

s = p[0]

statenames.append(s)

ax = plt.gca()

seg = map.states[statenames.index('四川')]

seg1 = map.states[statenames.index('湖南')]

seg2 = map.states[statenames.index('江苏')]

seg3 = map.states[statenames.index('上海')]

seg4 = map.states[statenames.index('安徽')]

seg5 = map.states[statenames.index('浙江')]

seg6 = map.states[statenames.index('北京')]

seg7 = map.states[statenames.index('山东')]

seg8 = map.states[statenames.index('江西')]

seg9 = map.states[statenames.index('广西')]

seg10 = map.states[statenames.index('湖北')]

poly = Polygon(seg,facecolor = 'crimson',edgecolor = 'r')

poly1 = Polygon(seg1,facecolor = 'crimson',edgecolor = 'r')

poly2 = Polygon(seg2,facecolor = 'crimson',edgecolor = 'r')

poly3 = Polygon(seg3,facecolor = 'violet',edgecolor = 'r')

poly4 = Polygon(seg4,facecolor = 'violet',edgecolor = 'r')

poly5 = Polygon(seg5,facecolor = 'violet',edgecolor = 'r')

poly6 = Polygon(seg6,facecolor = 'gold',edgecolor = 'r')

poly7 = Polygon(seg7,facecolor = 'gold',edgecolor = 'r')

poly8 = Polygon(seg8,facecolor = 'coral',edgecolor = 'r')

poly9 = Polygon(seg9,facecolor = 'coral',edgecolor = 'r')

poly10 = Polygon(seg10,facecolor = 'coral',edgecolor = 'r')

ax.add_patch(poly)

ax.add_patch(poly1)

ax.add_patch(poly2)

ax.add_patch(poly3)

ax.add_patch(poly4)

ax.add_patch(poly5)

ax.add_patch(poly6)

ax.add_patch(poly7)

ax.add_patch(poly8)

ax.add_patch(poly9)

ax.add_patch(poly10)

plt.show()
