Сбои в комбинированном графике Android Studio

Question

У меня ошибка и сбой приложения при нажатии на график.С одним LineChart или BarChart я могу нажать на вид или увеличение.

При реализации com.github.PhilJay:MPAndroidChart:v3.0.2

Вам нужно добавить mChart.setHighlightFullBarEnabled(false); или установить собственную подсветку при нажатии на гистограмму, для более подробной информации проверьте this
