##设置图片大小
plt.figure(figsize=(20,8),dpi=80)
##使用scatter方法绘制散点图，和之前绘制折线图的唯一区别
plt.scatter(x_3,y_3,label='3月份',color = '#F08080')
plt.scatter(x_10,y_10,label='10月份',color = 'cyan')
##调整X轴刻度
_x = list(x_3) + list(x_10)
_xtick_labels = ['3月{}日'.format(i) for i in x_3]
_xtick_labels += ['10月{}日'.format(i-50) for i in x_10]
plt.xticks(_x[::3],_xtick_labels[::3],rotation=60,fontproperties = my_font) ##取步长使X轴稀疏一点
##添加图例
plt.legend(loc = "upper left",prop = my_font)
## 添加描述信息
plt.xlabel("时间",fontproperties = my_font)
plt.ylabel("温度",fontproperties = my_font)
plt.title("3月份与10月份温度变化",fontproperties = my_font)
##保存图片
plt.savefig('y3.png')
## 展示
plt.show()
