Вопрос:
Я пытаюсь создать линейный график с помощью ChartJS. Однако я не могу динамически использовать многодатазеты. Эти данные генерируются случайным образом каждый день. Таким образом, в один и тот же день у меня могут быть два разных типа данных для одного и того же насекомого. Итак, из этого формата данных JSON мне нужно сгенерировать линейную диаграмму, на которой каждое насекомое имеет свою информацию по оси Y.
Возможно, я неправильно группирую данные. Но мы поняли, что необходимо иметь несколько наборов данных.
