Matplotlib是Python中的一個庫，它是數字的-NumPy庫的數學擴展。軸類包含大多數圖形元素：Axis，Tick，Line2D，Text，Polygon等，並設置坐標係。 Axes實例通過callbacks屬性支持回調。
matplotlib.axes.Axes.findobj()函數
matplotlib庫的axes模塊中的Axes.findobj()函數用於查找藝術家對象。
用法： Axes.findobj(self, match=None, include_self=True)
參數：此方法接受以下參數。
- match:此參數是匹配的過濾條件。默認值為無。
- include_self:此參數將self包含在要檢查是否匹配的列表中。
返回值：此方法返回藝術家(藝術家列表)。
以下示例說明了matplotlib.axes中的matplotlib.axes.Axes.findobj()函數：
