int idx = Chart2->Series[0]->GetCursorValueIndex();

TPoint            tpPosition;
    if(idx>=0)
    {
        double dX,dY;
        Chart2->Series[0]->GetCursorValues(dX, dY);
        Chart2->Hint="( "+FloatToStr(dX)+" , "+FloatToStr(dY)+ " )";

        GetCursorPos(&tpPosition);
        Application->ActivateHint(tpPosition);
    }
    else
    {
        Chart2->Hint="";
    }

만약 , Series가 여러개 일때는 어덯게 처리 하나요?
