저는 aChartEngine을 사용하여 일부 barchart를 생성했습니다. 하나의 활동 안에 9 개의 서로 다른 바카르트가 있습니다. 내 문제는 이들이 높은 경우 차트 값을 볼 수 없다는 것입니다.AChartAngine Barchart 줌 범위 밖의 값
layout_height 매개 변수를 fill_parent 또는 wrap_content로 변경하려고했습니다. 그러나 전체 차트는 보이지 않습니다. 따라서 layout_height에 대한 수정 값을 사용해야합니다.
하지만 차트를 변경하여 모든 차트 값을 보려면 어떻게해야합니까?
두 장의 사진을 첨부하겠습니다. 작은 값을 가진 barchart 중 하나와 표시되지 않는 큰 값을 가진 barchart 중 하나입니다.
사진 1 : Small values all looks good, 사진 2 : One big Value, Chart value is not displayed
