现在自定义生成图表是可以实现的，但是Y轴只能是数字类型的数据，我想要生成员工工号跟工作类别的图表，代码如何修改！
跪求帮助！急！谢谢！
筛选并汇总按钮的代码：
Dim Filter As String
Dim a = e.Form.Controls("TextBox1").Text
Dim b = e.Form.Controls("TextBox2").Text
With e.Form.Controls("DateTimePicker1")
If .value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "工作日期 >= #" & .text & "#"
End If
End With
With e.Form.Controls("DateTimePicker2")
If .value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "工作日期 <= #" & .text & "#"
End If
End With
If Filter > "" Then
Tables("工时").Filter = Filter
End If
Dim t As Table = Tables("工时")
Dim g As Subtotalgroup
t.SubtotalGroups.Clear()
t.GroupAboveData = False
t.TreeVisible = False
g = New Subtotalgroup
g.Aggregate = AggregateEnum.Sum
'g.GroupOn = "姓名"
g.Caption = "{0}"
t.SubtotalGroups.Add(g)
t.Subtotal()
Dim r As Row
For i As Integer = 0 To t.Rows.Count(True) - 1
r = t.Rows(i,True)
If r.IsGroup '如果是分组行
Dim f As String = "[" & a & "] = '" & r("[" & a & "]") & "'"
Dim v As String = " [" & b & "]:" & t.Compute("Sum([" & b & "])",f)
r("[" & a & "]") = "[" & a & "]:" & r("[" & a & "]") & v
End If
Next
Dim b1 As New GroupTableBuilder("统计表1",DataTables("工时"))
b1.Groups.AddDef("[" & a & "]","" & a & "") '添加日期列用于分组,并用"月"代替原名称
b1.Totals.AddDef("[" & b & "]") '添加数量列用于统计
b1.Subtotal = True '生成汇总模式
b1.Filter = Filter
b1.Build '生成统计表
MainTable = Tables("统计表1") '打开生成的统计表
生成图表代码：
Dim a = e.Form.Controls("TextBox1").Text
Dim b = e.Form.Controls("TextBox2").Text
Dim Chart As WinForm.Chart '定义一个图表变量
Dim Series As WinForm.ChartSeries '定义一个图系变量
Dim tbl As DataTable = DataTables("统计表1") '定义一个变量tbl引用数据表
Dim lst As List(Of String) = tbl.GetValues(a) '获得产品名称集合
Chart = e.Form.Controls("Chart1") ' 引用窗口中的图表
Chart.ChartType = ChartTypeEnum.Bar '图表类型该为Bar(条形)
Chart.SeriesList.Clear() '清除图表原来的图系
chart.AxisX.ClearValueLabel
Series = Chart.SeriesList.Add() '增加一个图系
Series.Length = lst.Count '设置图系的长度
Series.DataLabelText = "{#YVAL}"
For i As Integer = 0 To lst.Count - 1 '指定每个数据点的位置
Series.X(i) = i '指定水平坐标
Series.Y(i) = tbl.Compute("Sum(" & b & ")","[" & a & "] = '" & lst(i) & "'") '指定垂直坐标
Chart.AxisX.SetValueLabel(i, lst(i)) '指定字符表示
Next
Chart.AxisX.AnnoWithLabels = True '启用字符标示
