其他常用的图直接可以去官方网站找,然后套用即可



散点图

from matplotlib import pyplot as plt
from matplotlib import font_manager
y_3 = [11,17,16,11,12,11,12,6,6,7,8,9,12,15,14,17,18,21,16,17,20,14,15,15,15,19,21,22,22,22,23]
y_10 = [26,26,28,19,21,17,16,19,18,20,20,19,22,23,17,20,21,20,22,15,11,15,5,13,17,10,11,13,12,13,6]
x1=range(1,32)
x2=range(41,72)
plt.figure(figsize=(18,5),dpi=80)
_x=list(x1)+list(x2)
_xtick1=['3月{}日'.format(i) for  i in x1]
_xtick1+=['10月{}日'.format(i-40) for i in x2]
plt.xticks(_x[::3],_xtick1[::3],rotation=45)
plt.xlabel("时间")
plt.ylabel("温度")
plt.title("温度随时间的变化")
plt.scatter(x1,y_3,label='三月份')
plt.scatter(x2,y_10,label='十月份')
plt.grid(alpha=0.5)
plt.legend(loc='upper left')
plt.show()

散点图和折线图基本都一样
