我尽我所能坚持使用您的代码.解决方法如下:

I tried to stick to your code as much as I could. Here is the solution:

from matplotlib import pyplot
from descartes import PolygonPatch
import simplejson

def configurePlot():
    # set up the mapplotlib
    fig = pyplot.figure(1, figsize=(10, 4), dpi=180)
    ax = fig.add_subplot(121)
    return fig, ax


def setPlotExtent(ax, data):
    # get feature extents (a property of the cloudmade geojson)
    # note this was previously bbox
    minx = data['bounds'][0][0]
    maxx = data['bounds'][1][0]
    miny = data['bounds'][0][1]
    maxy = data['bounds'][1][1]

    # set the graph axes to the feature extents
    ax.set_xlim(minx, maxx)
    ax.set_ylim(miny, maxy)


def plotFeature(coordinates, myplot):
    poly = {"type": "Polygon", "coordinates": coordinates}
    patch = PolygonPatch(poly, fc='#6699cc', ec='#6699cc', alpha=0.5, zorder=2)
    # plot it on the graph
    myplot.add_patch(patch)


# turn the geojson into a python object
with open(r"file2.json") as f:
    pydata = simplejson.load(f)
print(pydata)

fig, myplot = configurePlot()
setPlotExtent(myplot, pydata)

plotFeature(pydata['coordinates'], myplot)

# save the plot as an image
pyplot.show()
fig.savefig('myplot.png')

和更正的json:
