exampleに基づいて、このコードはチャート内のポイントをドラッグするためのコードです。私はTimeSeriesオブジェクトをXYSeriesに置き換えたいと思っています。なぜなら、X軸で月を望んでいないからです。私はPoint1、Point2、Point3のような数字のシリーズを望んで、同じロジックをしたい。 XYSeriesと交換すると、XYSeriesのロジックを変更する方法がわかりません。JavaでTimeSeriesとTimeSeriesCollectionをそれぞれXYSeriesとXYCollectionに変更する方法は？

ありがとう非常に:) –
私はあなたが8セットのような別のクラスが提供するポイント数を設定したい場合は、2番目のものは、それはcreateDatasetにパラメータを提供することが可能です。他のクラスのポイント数を指定して、そのポイントに沿ってプロットできるようにしたい –
'createDataset（）'のパラメータとして渡すことがありますか？ – trashgod
