我的代码出错。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("发病图_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 '图表类型改为Bar(条形)
Chart.SeriesList.Clear() '清除图表原来的图系
For r As Integer = 0 To t.Rows.Count - 1
Series = Chart.SeriesList.Add() '增加一个图系
Series.Text = t.Rows(r)("确认学校") '设置图系的标题
Series.Length = t.Cols.Count - 2 '设置图系的长度
For c As Integer = 1 To t.Cols.Count - 1
Series.X(c) = c
Series.Y(c) = t.Rows(r)(t.Cols(c).Name)
Chart.AxisX.SetValueLabel(c, t.Cols(c).Name) '指定字符表示
Next
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)
