fig, ax = plt.subplots() ax.plot(x, y) # 绘制垂直线 ax.axvline(x=5, color='r', linestyle='--', label='vertical line') # 绘制水平线 ax.axhline(y=0, color='b', linestyle='-', label='horizontal line') 在上面的代码中,我们使用axvline函数绘制了一条垂直线,其位置由x=5指定。
Matplotlib plot line style You can change the line style in a line chart in python using matplotlib. You need to specify the parameterlinestylein theplot()function of matplotlib. There are several line styles available in python. You can choose any of them. You can either specify the name o...
