#python #matplotlib #график #легенда
Вопрос:
Я создаю подзаголовки python. У меня есть 10 фигур, и я хочу разместить легенду вне моего графика. После многих попыток я придумал этот код. Однако он помещает легенду посередине, что выглядит не очень красиво.

Может кто-нибудь, пожалуйста, предложить лучшее размещение?
Комментарии:
1. Посмотрите на примеры в matplotlib.org/users/legend_guide.html#legend-location ; обратите внимание, что подзаголовки объявлены, оставляя место для внешней легенды.
2. Я бы просто согласился
plt.legend(loc='lower left', ncol=3), хотя вы и не хотели, чтобы легенда была включена в сюжет. Другое дело, я бы построил серию в порядке «CS», «TD», а затем «HD», в этом случае порядок в легенде имеет тот же порядок, что и строки сверху вниз.3. Спасибо! это сработало!!
