DrillDown в множество линейни графики

Опитвам се да получа няколко линейни диаграми в един контейнер и да разреша разбивка във всяка от линейните графики. Но дори не мога да начертая различните линейни графики на ниво 0. Данните на втората линейна графика заместват първата, вместо да начертая две графики. Можете ли да ми помогнете с това?

Ето какво имам: връзка
