私が尋ねたものを検索すると、fusionchartsのウェブサイトに結果が表示されますが、探しているものが正確ではありません。ドリルダウンフュージョンチャートを同じページに作成
私はMySQLデータベースからデータをクエリし、このデータをフュージョンチャートに入れて自分のウェブページに表示しています。私は、同じページに2つのグラフが存在するようにしたい。親グラフのデータポイントの1つをクリックすると、子グラフは "ドリルダウン"グラフを表示する。これどうやってするの？現時点では親グラフを押すことができ、子グラフは新しいWebページ上に開きます。これは、親グラフを持つホームページのコードです。このファイルの名前は "dept.php"です。
