一.注释(annotate)
import matplotlib.pyplot as plt import numpy as np x = np.arange(-10,11,1) plt.plot(x,x*x) plt.annotate(s='the bottom',xy=(0,1),xytext=(0,20), arrowprops={ 'facecolor':'blue','headlength':8,'headwidth':10,'width':5}) plt.show()123456789
plt.annotate()----添加注释，s–注释标签，xy–头部位置，xytext–标签位置；
annotate()中注释采用箭头：给arrowprops字典赋值，facecolor–颜色，headlength–箭头部分长度，headwidth–箭头部分宽度，width–箭头身宽。
二.文字插入(text)
import matplotlib.pyplot as plt import numpy as np x = np.arange(-10,11,1) plt.plot(x,x*x) plt.text(x=-4,y=40,s='function:y=x*x',family='fantasy',size=20,color='green', style='italic',weight=1000,bbox={ 'facecolor'12345678
