我按照帮助文档中设置图表,但是在图系标题这里出现疑问,表中列名与图表的图系Text不同
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2") '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 '图表类型改为Bar(条形)
Chart.SeriesList.Clear() '清除图表原来的图系
For Each c As Col In t.Cols
If c.Name <> "科室" And c.Name <> "合计" Then
Series = Chart.SeriesList.Add() '增加一个图系
Series.Text = c.Name '设置图系的标题
Series.Length = t.Rows.Count '设置图系的长度
For r As Integer = 0 To t.Rows.Count - 1
Series.X(r) = r
Series.Y(r) = t.Rows(r)(c.Name)
Next
End If
Next
For r As Integer = 0 To t.Rows.Count - 1
Chart.AxisX.SetValueLabel(r, t.Rows(r)("科室")) '指定字符表示
Next
Chart.AxisX.AnnoWithLabels = True '启用字符标示
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.east '图列显示在南方(底端)
