matplotlib画多类型图增加图例保存图片设置坐标轴文字方向

大佬万福.请不吝赐教!

import matplotlib.pyplot as plt

data = pd.DataFrame(recallDict).T.reset_index()
data.columns = ['area','con','sug']

#设置横轴文字方向
plt.xticks(rotation=90)
#画叠加柱状图
plt.bar(data['area'], data['con'], color='#2F7336', label='controlRepeat')
plt.bar(data['area'], data['sug'], color='#F0CB35', label='suggestRepeat')
#增加图例
plt.legend()
#画图后保存
plt.savefig('freeDegree.jpg')

img = plt.show()
