Matplotlib es una biblioteca en Python y es una extensión matemática numérica para la biblioteca NumPy. La clase Axes contiene la mayoría de los elementos de la figura: Axis, Tick, Line2D, Text, Polygon, etc., y establece el sistema de coordenadas. Y las instancias de Axes admiten devoluciones de llamada a través de un atributo de devoluciones de llamada.
función matplotlib.axes.Axes.findobj()
La función Axes.findobj() en el módulo de ejes de la biblioteca matplotlib se usa para encontrar objetos de artistas.
Sintaxis: Axes.findobj(self, match=Ninguno, include_self=True)
Parámetros: este método acepta los siguientes parámetros.
- match : Este parámetro es el criterio de filtrado de las coincidencias. Su valor predeterminado es Ninguno.
- include_self : este parámetro se incluye a sí mismo en la lista para verificar si hay una coincidencia.
Devoluciones: este método devuelve artistas (lista de artistas).
Los siguientes ejemplos ilustran la función matplotlib.axes.Axes.findobj() en matplotlib.axes:
