专家坐堂-图表Y轴比例是否可以调整Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

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("抽签入围台帐_Table01") \'定义一个变量t引用数据表

Dim nms() As String = {"市内家数_比例","市外家数_比例"}

Chart = Forms("抽签入围台帐").Controls("Chart3") \' 引用窗口中的图表

Chart.AxisY.Min = 0 \'指定Y轴的最小值

Chart.AxisY.Max = 100 \'指定Y轴的最大值

Chart.HeaderText = "报名家数比例" \'生成Chart总图名称

Chart.AxisX.ClearValueLabel \'清除所有通过SetValueLabel设置的数值字符标示

Chart.SeriesList.Clear() \'清除图表原来的图系

t.Sort = "抽签日期 DESC"

For Each c As String In nms

Series = Chart.SeriesList.Add() \'增加一个图系

Series.Text = c \'设置图系的标题

Series.Length = t.Rows.Count \'设置图系的长度
