大家在编写ASP程序的时候，可能要对各种指标以图形的方式显示出来。如果仅仅是柱状图，可以采用画表格的方法。许多投票程序多采用这种方法。如果是饼状图或从数据库中检索数据后再显示，就有些困难了.办法也有，自己可以封装excel来完成上述功能，或者用deiphi做一个activeform传入参数,或者用php来写,java也可以。当然，用一个比较成熟的图形组件来完成更好一些。microsoft office web compoent非常不错。我在开发一个项目的时候，用到了这个组件。 CHART.ASP程序。 <% Option Explicit %> <!--#include file="adovbs.inc"--> <HTML> <HEAD> <TITLE>柱状图的例子</TITLE> <% Function ExportChartToGIF(objCSpace, strAbsFilePath, strRelFilePath) Dim strFileName Randomize strFileName = Timer & Rnd & ".gif" objCSpace.ExportPicture strAbsFilePath & "/" & strFileName, "gif", 650, 400 ExportChartToGIF = strRelFilePath & "/" & strFileName End Function Sub CleanUpGIF(GIFpath) Dim objFS Dim objFolder Dim gif set objFS = Server.CreateObject("Scripting.FileSystemObject") set objFolder = objFS.GetFolder(GIFpath) for each gif in objFolder.Files if instr(gif.Name, ".gif") > 0 and DateDiff("n", gif.DateLastModified, now) > 10 then objFS.DeleteFile GIFpath & "/" & gif.Name, True end if next set objFolder = nothing set objFS = nothing End Sub %> </HEAD> <BODY BGCOLOR="#FFFFFF"> <div align="center"> <br> <br> <% dim sj1,sj2 sj1=Request.QueryString("s1") sj2=Request.QueryString("s2") dim objChartSpace dim objChart dim objSeries dim objConn dim objRS dim c dim series dim strChartAbsPath dim strChartRelPath dim strChartFile dim axis strChartAbsPath = Server.MapPath("/xjsi-web/dcss/chart") strChartRelPath = "/xjsi-web/dcss/chart" '设置组件 set objChartSpace = Server.CreateObject("OWC.Chart") set objChart = objChartSpace.Charts.Add set c = objChartSpace.Constants objChartSpace.Border.Color="red" '以柱状图显示 objchart.type=1 objChart.HasLegend = True'是否显示图例 objChartSpace.HasChartSpaceTitle=true '显示标题 objChartSpace.ChartSpaceTitle.Caption ="柱状图的例子使用office web组件--www.ourfly.com中文技术网站" set objConn = Server.CreateObject("ADODB.Connection") objConn.Open application("strconn") set objRS = Server.CreateObject("ADODB.Recordset") set objRS.ActiveConnection = objConn objRS.CursorType = adOpenStatic objRS.CursorLocation = adUseClient objRS.Open "select dwsj,sum(jfrs) as jfrs from dcss_do_jfgcfxb where dwsj>='"&sj1&"' and dwsj<'"&sj2&"' group by dwsj order by dwsj asc" set objChartSpace.DataSource = objRS '显示图例内容 objChart.SetData c.chDimSeriesNames, 0, "jfrs" for each objSeries in objChart.SeriesCollection objSeries.SetData c.chDimCategories, 0, "dwsj" objSeries.SetData c.chDimValues, 0, "jfrs" next for each axis in objChart.Axes axis.HasTitle = True if axis.Type = c.chCategoryAxis then axis.Title.Caption = "月份" else axis.Title.Caption = "人数" end if next strChartFile = ExportChartToGIF(objChartSpace, strChartAbsPath, strChartRelPath) Response.Write "<IMG SRC=""" & strChartFile & """>" & "<P>" CleanUpGIF strChartAbsPath objRS.Close set objRS = nothing set objConn = nothing set objSeries = nothing set objChart = nothing set objChartSpace = nothing %> </div> </BODY> </HTML> 使用这个组件的注意事项： 1。在office2000的光盘上，有一个msowc.msi的可执行文件.OK 2。建议大家用visual interdev6.0开发，代码的自动提示功能此时会发挥出极大的作用。 效果图如下：
