是否可以显示绑定图表的注释？我能够创建一个绑定图表，但是当我尝试显示注释时，它根本不起作用。下面是我使用的代码。

con = ConnectDB()

        Try
            con.Open()
            da = New SqlDataAdapter("WITH tempLotTracking AS(SELECT TOP 5 * FROM tblLotTracking ORDER BY LotTrackingID DESC) SELECT * FROM tempLotTracking ORDER BY LotTrackingID", con)
            da.Fill(ds, "tblLotTracking")
            con.Close()
        Catch ex As Exception
            con.Close()
            MsgBox("Error connecting to database.", MsgBoxStyle.Critical)
            MsgBox(ex.ToString)
            Exit Sub
        End Try

        Chart1.Series("Series1").XValueMember = "WorkWeek"
        Chart1.Series("Series1").YValueMembers = "TotalIssues"

        Dim myLine As LineAnnotation = New LineAnnotation()
        myLine.Name = "myLine"
        myLine.X = 3
        myLine.Y = 3
        Chart1.Annotations.Add(myLine)

        Chart1.DataSource = ds.Tables("tblLotTracking")

您可能需要在图表注释上放置锚点：-

   myLine.AnchorX = some_value
   myLine.AnchorY = some_other_value

并且还要检查你没有做我所做的事情并以背景颜色绘制注释文本。
