最简单的方法是使用plt.text()函数在垂直线旁边添加文本: importmatplotlib.pyplotaspltimportnumpyasnp x=np.linspace(0,10,100)y=np.sin(x)*np.exp(-0.1*x)plt.figure(figsize=(10,6))plt.plot(x,y,label='Damped sine wave')# 添加带标签的垂直线line=plt.axvline(x=5,color='r',linestyle='-...
Method 2: Using the dashes parameter: The Seaborn lineplot() has a dashes parameter that also helps set custom lines for the line plot. Here is a code snippet showing how to use it. import seaborn as sns import numpy as np import matplotlib.pyplot as plt import pandas as pd s = 90 g...
