主题：关于作图，请教下如何做一行记录的图表

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("营养素作图统计表") '定义一个变量t引用数据表
Chart= Forms("统计图").Controls("Chart1") ' 引用窗口中的图表
Chart.VisualEffect = True '加上这一行,让你的图表更漂亮
Chart.ChartType = ChartTypeEnum.Pie '图表1类型改为Bar(条形)
Dim r As Row = t.Current
For Each c As Col In t.Cols
    If c.Name <> "日期" Then
        Series = Chart.SeriesList.Add() '增加一个图系
        Series.Length = 1 '一个系列只能包括一个值
        Series.Text = c.name & "(" & r(c.name) & ")" '设置图系的标题
        Series.Y(0) = r(c.name) '指定值
    End If
Next
Chart.LegendVisible = True '显示图列
Chart.LegendCompass= CompassEnum.East '图列显示在东方(右方)

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("营养素作图统计表") '定义一个变量t引用数据表
Chart= Forms("统计图").Controls("Chart1") ' 引用窗口中的图表
Chart.VisualEffect = True '加上这一行,让你的图表更漂亮
Chart.ChartType = ChartTypeEnum.Pie '图表1类型改为Bar(条形)
Dim r As Row = t.Current
Dim cs() As String = {"碳水化合物","脂肪","蛋白质"}
For Each c As String In cs
    Series = Chart.SeriesList.Add() '增加一个图系
    Series.Length = 1 '一个系列只能包括一个值
    Series.Text = c & "(" & r(c) & ")" '设置图系的标题
    Series.Y(0) = r(c) '指定值
Next
Chart.LegendVisible = True '显示图列
Chart.LegendCompass= CompassEnum.East '图列显示在东方(右方)

加上代码

Series.DataLabelText = c & "(" & r(c) & ")"

 这两句删除

Chart.LegendVisible = True '显示图列
Chart.LegendCompass= CompassEnum.East '图列显示在东方(右方)

Dim Chart As WinForm.Chart '定义一个图表变量

Chart.VisualEffect = True '加上这一行,让你的图表更漂亮
Chart.ChartType = ChartTypeEnum.Pie '图表1类型改为Bar(条形)
Dim r As Row = t.Current
Dim sum As Double = r("碳水化合物") + r("脂肪") + r("蛋白质")
Dim cs() As String = {"碳水化合物","脂肪","蛋白质"}
For Each c As String In cs
    Series = Chart.SeriesList.Add() '增加一个图系
    Series.Length = 1 '一个系列只能包括一个值
    Series.DataLabelText = c & "(" & Format(r(c)/sum, "0.00%") & ")"
   
    Series.Y(0) = r(c) '指定值
Next
