老师，您好：
根据如下 统计表，生成图表时，在红色标记的For Loop内，当 c 增到 8 时，就会报错：指定的参数已超出有效值的范围！
你能帮着看下是什么问题吗？十分感谢！
‘#生成图表Code:
Dim Chart As WinForm.Chart
Dim Series As WinForm.ChartSeries
Dim t As Table = Tables("数据汇总_Table1") \'定义一个变量t引用数据表
Chart = e.Form.Controls("Chart1")
Chart.VisualEffect = False
Chart.SeriesList.Clear()
Chart.AxisY.Min = 0
Chart.AxisY.Max = 5
For r As Integer = 0 To t.Rows.count - 1
Series = Chart.SeriesList.Add()
Series.Text = t.rows(r)("样品批号")
Series.Length = t.Cols.Count - 7 \'设置图系的长度
For c As Integer = 7 To t.Cols.count - 1
Series.X(c - 1) = c - 1
Series.Y(c - 1) = t.Rows(r)(c)
Next
Next
Chart.AxisX.AnnoWithLabels = True \'启用字符标示
Chart.LegendVisible = True \'显示图列
Chart.LegendCompass= CompassEnum.South \'图列显示在南方(底端)
