主题：[求助] 关于Chart的饼状图显示不完整

老师，以下是代码，我将字体改小了，就可以全部显示出来，应该是字体太大而导致的，但是字体必须要这么大，有没有什么办法解决呢？
Dim tb As Table = Tables(e.Form.Name & "_Table1")
Dim dt As DataTable = tb.DataTable

Dim g As New GroupTableBuilder("统计表1", dt)
g.Groups.AddDef("Sum")
g.Totals.AddDef("单据编号", AggregateEnum.Count)
g.Totals.AddDef("返工人数")
g.Totals.AddDef("返工工时")
g.Totals.AddDef("人力成本")
g.Totals.AddDef("物料费用")
g.Totals.AddDef("总费用")
Tables(e.Form.Name & "_Table2").DataSource = g.BuildDataSource

Dim tb3 As Table = Tables(e.Form.Name & "_Table3")
Dim g1 As New GroupTableBuilder("统计表2", dt)
g1.Groups.AddDef("责任部门")
g1.Totals.AddDef("责任人", AggregateEnum.Count,"责任次数")
g1.Totals.AddDef("总费用")
g1.GrandProportion = True
tb3.DataSource = g1.BuildDataSource
tb3.Sort = "总费用gdr"
tb3.SetColVisibleWidth("责任部门|73|责任次数|61|总费用|55|总费用gdr|83")

Dim Series As WinForm.ChartSeries '定义一个图系变量
Dim Chart As WinForm.Chart = e.Form.Controls("Chart1")
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)
Chart.SeriesList.Clear() '清除图表原来的图系
Chart.VisualEffect = True
For Each r As Row In tb3.Rows
    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 = r("责任部门") '设置图系的标题
    Series.Y(0) = r("总费用gdr") '指定值
    Series.DataLabelText = r("责任部门") & Math.Round(r("总费用gdr")*100,2) & "%" '计算百分比
Next
Chart.LegendVisible = True '显示图列
Chart.LegendCompass= CompassEnum.East '图列显示在东方(右方)
