HighForts подсказка pointFormat

Question

Ниже приведен мой код для комбинированного графика Yii 1, включающего круговую диаграмму, гистограмму и линейный график.Для линейного графика я хочу отобразить точку после простого деления на 10 (то есть, если значение точки равно 60, оно должно отображать 6, когда курсор находится над этой точкой).Но с моим приведенным ниже кодом он отображается как 60/10 вместо 6. Кроме того, я хочу, чтобы это деление было сделано только для линейного графика, а не для двух других графиков.Пожалуйста, помогите мне решить эту проблему.
