终于搞出来了。
本年：
Dim g As New GroupTableBuilder("统计表12", DataTables("采购明细"))
Dim y As Integer = Date.Today.Year
Dim dt1 As New Date(y, 1, 1)
Dim dt2 As New Date(y, 12, 31)
Dim Filter As String
Filter = "采购日期 >= #" & dt1 & "# And 采购日期 <= #" & dt2 & "#"
g.Groups.AddDef("采购日期", DateGroupEnum.Year, "年")
g.Groups.AddDef("采购日期", "月")
g.Totals.AddDef("数量", "", "数量_值")
g.Totals.AddDef("金额", "", "金额_值")
g.SamePeriodGrowth = True
g.CircleGrowth = True
g.filter=filter
Tables("进货分析_Table1").DataSource = g.BuildDataSource()
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("进货分析_Table1")
Chart= e.Form.Controls("Chart1") ' 引用窗口中的图表
Chart.SeriesList.Clear() '清除图表原来的图系
Series = Chart.SeriesList.Add() '增加一个图系
Series.Length = t.Rows.Count '图系的数据点数等于表的行数
For i As Integer = 0 To t.Rows.Count - 1 '指定每个数据点的位置
Series.X(i) = t.Rows(i)("月") '指定水平坐标
Series.Y(i) = t.Rows(i)("金额") '指定垂直坐标
Next
Chart.SeriesList(0).LineColor= Color.Red
Series.MarkColor = Color.GREEN
