老师，辅助线图例，现在是这个效果，怎么才能不会执行一次就增加一个呢。。
'增加均值
Dim r As Row =forms("人脸识别年龄段统计").Controls("table1").Table.Rows(0)
Dim dj As Single = r("成交率_店均")
Dim C1Cha As C1.Win.C1Chart.C1Chart = Chart.BaseControl
Dim tl As C1.Win.C1Chart.TrendLine = C1Cha.ChartGroups(0).ChartData.TrendsList.AddNewTrendLine()
tl.LineStyle.Color = Color.black '线条颜色
tl.LineStyle.Thickness = 2 '线宽
tl.LineStyle.Pattern = 0 '直线样式 0-5
Dim zxb = New zxb柱状图标辅助线()
zxb.SetXY(New PointF(-0.5,dj),New PointF(Series.Length,dj))
zxb.SetText("多店整体成交率")
tl.CustomTrendLine = zxb
