C# диаграмма Сетка оси Y и прокрутка меток

Question

Я борюсь с графическим дисплеем MS C# и прокруткой по оси Y. Что я хочу сделать, так это то, что когда я сдвигаю полосу прокрутки оси Y, основной слайд сетки тоже. Но основная сетка фиксирована, а ярлык меняется. Ось Y - это «стиль номера». Ось X - это стиль «datetime». Когда я прокручиваю ось X, прокручивается дата. Это хорошо синхронизировано. Но это не так для оси Y. Я пытаюсь изменить YAxis.LabelStyle и YAxis.MajorGrid без успеха.

У вас есть идея сделать это. Он хорошо работает для оси X без какого-либо кода, но не для оси Y. Я думаю, что можно что-то сделать с событием AxisChanged, но довольно сложно. Надеюсь, мой вопрос ясен! Английский язык не мой любимый язык!

Answer 1

Некоторые обновления для моей проблемы.

Я добавил обработчик событий в AxisViewChanged. В этом случае обработчик i обновляет метку, сетку и интервал по оси Y в зависимости от значения AxisY.ScaleView.ViewMinimum.

Этот обработчик событий также изменяет размеры вторичной оси относительно увеличения по оси Y.
