Requisito previo: crear y escribir en un archivo de Excel. XlsxWriter es una biblioteca de Python con la que se pueden realizar múltiples operaciones en archivos de Excel, como crear, escribir, operaciones aritméticas y trazar gráficos. Veamos cómo trazar diferentes tipos de gráficos de dispersión utilizando datos en tiempo real. Los gráficos se componen de al menos una serie de uno o más puntos de datos. Las series en sí mismas se componen de referencias a rangos de celdas. Para trazar los gráficos en una hoja de Excel, en primer lugar, cree un objeto de gráfico de un tipo de gráfico específico (es decir, Scatter, etc.). Después de crear objetos de gráfico, inserte datos en él y, por último, agregue ese objeto de gráfico en el objeto de hoja. Código #1:Trace el gráfico de dispersión simple. Para trazar el gráfico de dispersión simple en una hoja de Excel, use el método add_chart() con el argumento de palabra clave de tipo ‘Dispersión’ de un objeto de libro de trabajo.
