点击提取按钮就会生成统计表和图表
提取按钮代码如下：
Dim Filter As String
Dim mc As Integer = e.Form.Controls("TextBox1").value
With e.Form.Controls("DateTimePicker1")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "日期 >= #" & .Value & "#"
End If
End With
With e.Form.Controls("DateTimePicker2")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "日期 <= #" & .Value & "#"
End If
End With
With e.Form.Controls("ComboBox1")
If .Value IsNot Nothing Then
If Filter > "" Then
Filter = Filter & " And "
End If
Filter =Filter & "发站 = '" & .Value & "'"
End If
End With
With e.Form.Controls("ComboBox2")
If .Value IsNot Nothing Then
If Filter > "" Then
Filter = Filter & " And "
End If
Filter =Filter & "到站 = '" & .Value & "'"
End If
End With
Tables("货量排名_table1").Filter = Filter
Dim a As String
Dim b As String = "运费合计"
If e.Form.Controls("RadioButton1").Checked = True Then
a = "发货人"
Else If e.Form.Controls("RadioButton2").Checked = True Then
a = "收货人"
End If
Dim t As Table = Tables("所有开单记录库")
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("所有开单记录库"))
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
Tables("统计表1").Sort = "运费合计"
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
能帮忙解决下吗？谢谢老师！
