简单可以这样改
Dim Value() As String
Value = e.Node.FullPath.Split("\")
Select Case e.Node.Level
Case 0
Tables("统计表1").Datatable.LoadFilter ="[单位] = '" & Value(0) & "'"
Tables("统计表1").Datatable.Load
End Select
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
Chart = e.Form.Controls("Chart2") ' 引用窗口中的图表
Chart.ChartType = ChartTypeEnum.Bar '图表类型改为Bar(条形)
Chart.DataSource = "统计表1" '设置绑定表
Chart.SeriesList.Clear() '清除图表原来的图系
For Each c As Col In t.Cols
If c.Name <> "单位" Then
Series = Chart.SeriesList.Add() '增加一个图系
Series.Text = c.Name '设置图系的标题
Series.X.DataField = "单位" 'X轴绑定到产品列
Series.Y.DataField = c.Name '设置Y轴的绑定列
End If
Next
Chart.VisualEffect = True '加上这一行,让你的图表更漂亮
Chart.LegendVisible = True '显示图列
Chart.LegendCompass= CompassEnum.South '图列显示在南方(底端)
Chart.AxisX.AnnoRotation = - 45 'X轴标示逆时针旋转45度
