参考:Add a vertical slider with matplotlib Matplotlib是Python中最流行的数据可视化库之一,它提供了丰富的绘图功能。然而,在某些情况下,我们可能希望能够动态地调整图表的某些参数,以便更好地探索和分析数据。这就是滑块控件发挥作用的地方。在本文中,我们将深入探讨如何在Matplotlib中添加垂直滑块,以增强图表的交互性和...
axhline函数是Matplotlib中用于绘制水平线的专用函数。它的基本语法如下: importmatplotlib.pyplotasplt plt.figure(figsize=(8,6))plt.axhline(y=0.5,color='r',linestyle='--')plt.title('Basic axhline Example - how2matplotlib.com')plt.ylim(0,1)plt.show() ...
