主题：图表排序

你这种，需要先分组生成数据，然后排序，然后再生成图表

Dim d As Date = Date.Today
Dim d1 As Date = new Date(2019, d.month,  26)
Dim d2 As Date = new Date(2019, d.month, 25)
Dim d3 = d1.AddMonths(-2)
Dim d4 = d1.AddMonths(-1)
Dim g As New GroupTableBuilder("统计表1", DataTables("月报表"))
g.Filter = "日期 >= '" & Format(d3, "MM.dd") & "' and 日期 < '" & Format(d4, "MM.dd") & "'"
g.Groups.AddDef("供应商")
g.Totals.AddDef("供应商", AggregateEnum.Count, "不合格批次")
Tables("窗口1_Table1").DataSource = g.BuildDataSource()
Tables("窗口1_Table1").sort = "不合格批次 desc"
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("窗口1_Table1") '定义一个变量t引用数据表
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.HeaderText = d4.month & "月"
Chart.AxisX.Major = 2
Chart.AxisY.Major = 2
Chart.AxisY.Min = 0
Chart.SeriesList.Clear() '清除图表原来的图系
Chart.AxisX.ClearValueLabel
Series = Chart.SeriesList.Add() '增加第一个图系
Series.Length = t.Rows.Count '图系的数据点数等于表的行数
Dim count = iif(t.Rows.count > 7, 7, t.Rows.count)

Series.X(0) = 0 '指定水平坐标
Series.Y(0) = 0
Chart.AxisX.SetValueLabel(0, "")

For i As Integer = 0 To count- 1 '指定每个数据点的位置
    Series.X(i+1) = i+1 '指定水平坐标
    Series.Y(i+1) = t.Rows(i)("不合格批次") '指定垂直坐标
    Chart.AxisX.SetValueLabel(i+1, t.Rows(i)("供应商"))
Next
Chart.AxisX.AnnoWithLabels = True '启用字符标示
Chart.LegendCompass= CompassEnum.South '图列显示在南方(底端)
Series.DataLabelText = "{#YVAL}"
Chart.AxisX.AnnoRotation = -45 'X轴标示逆时针旋转45度

请发具体实例上来测试。

    Series1.DataLabelText = Math.Round(Series1.Y(0)*100/sm1,2) & "%" '计算百分比

dr=DataTables("物料不合格明细").find("日期 = #" & filter & "#")

改成

dr=DataTables("物料不合格明细").find(filter)
