Respecto al problema de la subimagen del gráfico de estrategia
En el lenguaje python, ¿se pueden crear varios subgráficos? Deseo que los diferentes indicadores de cálculo se muestren en diferentes subgráficos para facilitar el análisis. Actualmente, el gráfico de estrategias solo tiene un subgráfico, y los diferentes indicadores de cálculo en el subgráfico se muestran en un subgráfico mediante la traza de gráficos.
