数据源以及想要的目标效果见附图，实际的效果图也见附图

注：通过代码形式生成，不通过绑定的形式生成

有点蓝老师，我参照做了一个代码，如下：

Dim Chart As WinForm.Chart

Dim Series As WinForm.ChartSeries

Chart = e.Form.Controls("Chart2")

Chart.VisualEffect = True

Chart.ChartType = ChartTypeEnum.Bar

Chart.DataSource = "熔炼效率"

Chart.SeriesList.Clear()

Series = Chart.SeriesList.Add()

Series.Text = "一班熔速"

Series.X.DataField = "铸锭批号"

Series.Y.DataField = "熔炼1_熔速kgph"

Series.Length = t.Rows.Count '设置图系的长度

For i As Integer = 0 To t.Rows.Count - 1 '指定每个数据点的位置

Series.X(i) = i '指定水平坐标

Series.Y(i) = t.Rows(i)("熔炼1_熔速kgph") '指定垂直坐标

Chart.AxisX.SetValueLabel(i, t.Rows(i)("铸锭批号")) '指定字符表示

Chart.AxisX.AnnoWithLabels = True

但是显示：t是private ，因此在上下文中不可引用

错误代码：For i As Integer = 0 To t.Rows.Count - 1

Dim Chart As WinForm.Chart
Dim Series As WinForm.ChartSeries
Chart = e.Form.Controls("Chart2")
Chart.VisualEffect = True
Chart.ChartType = ChartTypeEnum.Bar
Chart.DataSource = "熔炼效率"
Chart.SeriesList.Clear()
Series = Chart.SeriesList.Add()
Series.Text = "一班熔速"
Series.X.DataField = "铸锭批号"
Series.Y.DataField = "熔炼1_熔速kgph"

或者这样

Dim Chart As WinForm.Chart
Dim Series As WinForm.ChartSeries
Chart = e.Form.Controls("Chart2")
Chart.VisualEffect = True
Chart.ChartType = ChartTypeEnum.Bar
dim t as table = tables("熔炼效率")
Chart.SeriesList.Clear()
Series = Chart.SeriesList.Add()
Series.Text = "一班熔速"
Series.Length = t.Rows.Count '设置图系的长度
For i As Integer = 0 To t.Rows.Count - 1 '指定每个数据点的位置
    Series.X(i) = i '指定水平坐标
    Series.Y(i) = t.Rows(i)("熔炼1_熔速kgph") '指定垂直坐标
    Chart.AxisX.SetValueLabel(i, t.Rows(i)("铸锭批号")) '指定字符表示
Next
Chart.AxisX.AnnoWithLabels = True
