--  [求助]折线图百分比格式
当折线图是多图系时,下面怎么改
Dim c1Chart1 = Chart.basecontrol
Dim lbls = c1Chart1.ChartLabels
For i As Integer = 0 To 12
    Dim lbl As C1.Win.C1Chart.Label = lbls.LabelsCollection.AddNewLabel()
    lbl.Text = Format(series.y(i), "0.00%")
    lbl.AttachMethod = C1.Win.C1Chart.AttachMethodEnum.DataIndex
    lbl.AttachMethodData.GroupIndex = 0
    lbl.AttachMethodData.SeriesIndex = 0
    lbl.AttachMethodData.PointIndex = i
    If Series.Y(i) >= 0 Then
        lbl.Style.ForeColor = Color.Black
    Else
        lbl.Style.ForeColor = Color.Red
    End If
    lbl.style.font = New font("宋体", 15)
    lbl.Compass = LabelCompassEnum.North
    lbl.Visible = True
Next

两条折线的时候,只有其中一条设置了百分比格式,另一条没成功。数据点的位置也不对,不知道如何调整

Chart.SeriesList.Clear() 这里没起作用,切换数据的时候数据标示仍会重叠
