내가 물었던 것을 검색하면 fusioncharts 웹 사이트에서 결과를 얻을 수 있지만 정확히 무엇을 찾고있는 것이 아닙니다.동일한 페이지에서 드릴 다운 퓨전 차트 만들기
나는 MySQL 데이터베이스의 데이터를 쿼리하고이 데이터를 융합 차트에 넣어 웹 페이지에 표시합니다. 동일한 페이지에 2 개의 그래프가 있어야하고 부모 그래프의 데이터 점 중 하나를 클릭하면 하위 그래프에 "드릴 다운"그래프가 표시됩니다. 어떻게해야합니까? 현재 부모 그래프를 누르면 새 웹 페이지에서 자식 그래프가 열립니다. 상위 그래프가있는 홈 페이지의 코드입니다. 이 파일의 이름은 "dept.php"입니다.
