在使用python Basemap绘制地图并给特定地区染色的过程中,有些地区无法上色。请问各位大神有无解决方法?
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

大神的教程。

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()
只画山东和浙江的例子
