使用Office2000中的图表控件绘制图形~

来源：互联网发布：linux 自动获取ip 编辑：程序博客网时间：2024/05/22 05:31

      示例中使用 ADO 记录集中的数据创建图表。首先根据返回的记录集数据创建以制表符分隔的字符串，然后通过 SetData 方法并使用此字符串设置图表数据。
       下面用的数据结构如图：

这个，可以从SQL Server里面的自带的数据库导过来。

<object id="ChartSpace1" classid="CLSID:0002E500-0000-0000-C000-000000000046" style="width:80%;height:350"></object>
<object id="ADOConnection1" runat="server" classid="CLSID:00000514-0000-0010-8000-00AA006D2EA4"></object>
这里的ADOConnection1可以通过Server.CreateObject("ADODB.Connection")来创建，不过ChartSpace在服务器端的创建，我太清楚，所以就用客户端的创建方式。

Dim rs, categories, values
categories = ""
values = ""

'打开连接执行sql查询 (建立“nwind.mdb”库，并创建名为“Category Sales for 1997”的表)
ADOConnection1.ConnectionString = "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.MapPath("nwind.mdb")
ADOConnection1.Open

Set rs = ADOConnection1.Execute("SELECT * FROM [Category Sales for 1997]")
'对于每一字段记录产生一个由制表符分隔的字符串
rs.MoveFirst
Do while Not rs.EOF
  categories = categories & rs.Fields(0).Value & Chr(9)
  values = values & rs.Fields(1).Value & Chr(9)
  rs.MoveNext
Loop
rs.Close
ADOConnection1.Close

'删去字符串末尾的分隔符
categories = Left(categories, Len(categories) - 1)
values = Left(values, Len(values) - 1)
