想实现 选择 相应型号，以及起始日期以后，针对“故障”数量形成图表。下列代码不知道问题出在哪里了。

Dim g As New GroupTableBuilder("统计表1", DataTables("检测维修单"))
g.Groups.AddDef("故障")
g.Totals.AddDef("业务编号", AggregateEnum.Count, "数量")
g.Build()
Dim Filter As String
With e.Form.Controls("combobox1")
    If .Value IsNot Nothing Then
        Filter = Filter & "型号 like \'*" & .Value & "*\'"
         End If
End With

With e.Form.Controls("StartDate")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "接修日期 >= #" & .Value & "#"
    End If
End With
With e.Form.Controls("EndDate")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "接修日期 <= #" & .Value & "#"
    End If
End With

If Filter > "" Then
    Tables("检测维修单").Filter = Filter
End If
MainTable = Tables("统计表1")

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 t As Table = Tables("统计表1") \'定义一个变量t引用数据表
Dim sm As Integer = t.Compute("Sum(数量)") \'计算总数量
Chart = e.Form.Controls("Chart1") \' 引用窗口中的图表
Chart.VisualEffect = True \'加上这一行,让你的图表更漂亮
Chart.ChartType = ChartTypeEnum.Pie \'图表1类型改为Bar(条形)
For Each r As Row In t.Rows
    Series = Chart.SeriesList.Add() \'增加一个图系
    Series.Length = 1 \'一个系列只能包括一个值
    Series.Text = r("故障") & "(" & r("数量") & ")" \'设置图系的标题
    Series.Y(0) = r("数量") \'指定值
    Series.DataLabelText = Math.Round(r("数量")*100/sm,2) & "%" \'计算百分比
Next
Chart.LegendVisible = True \'显示图列
Chart.LegendCompass= CompassEnum.East \'图列显示在东方(右方)

 你是不是这个意思？

Dim Filter As String
With e.Form.Controls("combobox1")
    If .Value IsNot Nothing Then
        Filter = Filter & "型号 like \'*" & .Value & "*\'"
         End If
End With

With e.Form.Controls("StartDate")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "接修日期 >= #" & .Value & "#"
    End If
End With
With e.Form.Controls("EndDate")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "接修日期 <= #" & .Value & "#"
    End If
End With

MainTable = Tables("统计表1")

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 t As Table = Tables("统计表1") \'定义一个变量t引用数据表
Dim sm As Integer = t.Compute("Sum(数量)") \'计算总数量
Chart = e.Form.Controls("Chart1") \' 引用窗口中的图表
Chart.VisualEffect = True \'加上这一行,让你的图表更漂亮
Chart.ChartType = ChartTypeEnum.Pie \'图表1类型改为Bar(条形)
For Each r As Row In t.Rows
    Series = Chart.SeriesList.Add() \'增加一个图系
    Series.Length = 1 \'一个系列只能包括一个值
    Series.Text = r("故障") & "(" & r("数量") & ")" \'设置图系的标题
    Series.Y(0) = r("数量") \'指定值
    Series.DataLabelText = Math.Round(r("数量")*100/sm,2) & "%" \'计算百分比
Next
Chart.LegendVisible = True \'显示图列
Chart.LegendCompass= CompassEnum.East \'图列显示在东方(右方)

恩，我的思路是先筛选 日期和姓名  然后根据故障的数量来做表 ，但是出来的图表，打上日期却没用

Chart.ChartType = ChartTypeEnum.Pie \'图表1类型改为Bar(条形)
