pyplot绘制图形，barh绘制横向柱状图，排序问题，x,y均已排序好，但是绘制图形时还是按照顺序来显示
Tuplex = zip(np.array(ans/100), range(len(ans)))
tempTuple = sorted(Tuplex, reverse=True)
x = [i[1] for i in tempTuple]
y = [i[0] for i in tempTuple]
print(x)
print('___________________')
print(y)
pyplot.barh(x, y)
pyplot.yticks(ticks=x)
pyplot.title(" Feature importances")
pyplot.show()
