Python中的 Matplotlib.axis.XAxis.get_figure()函数
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。
Matplotlib.axis.XAxis.get_figure()函数
matplotlib库的axis模块中的XAxis.get_figure()函数用于获取艺术家所属的Figure实例。
Syntax: XAxis.get_figure(self)
Parameters: This method does not accepts any parameter.
Return value: This method return the Figure instance the artist belongs to.
