Python中的 Matplotlib.axis.Axis.findobj()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.Axis.findobj()函数
matplotlib 库的轴模块中的Axis.findobj()函数用于查找艺术家对象。
Syntax: Axis.findobj(self, match=None, include_self=True)
Parameters: This method accepts the following parameters.
- match : This parameter is the filter criterion for the matches. It default value is None.
- include_self : This parameter include self in the list to be checked for a match.
Return value: This method return the artists(list of Artist).
