диаграмма разметки основного участка графика x y не отображается правильно

Question

Я попытался построить операцию с использованием названия месяцев с некоторыми данными по оси y. Я хотел, чтобы у показать данные, такие как 20, 40, 50, 60, ... 120, а х должен был быть только январь, февраль, март Это то, что я хочу

и это то, что я получаю

Click This link here Кто-то знает, как исправить это, пожалуйста?

xValues, Y. только NSMutables с данными xValues ​​[0, 5, 15, 20 ... 50 ... 60 ... 70 ..] [60, Y., 70, 80, 50, 40 ....]

Изменить любые ссылки на _hostView.hostedGraph.graph к _hostView.hostedGraph. Свойство наследуется от CPTLayer. Он используется другими частями графика для сохранения указателя на график, но не самого графика.
