所以我有一些VBA采取与窗体的图表向导建立图表，并自动将其插入到PowerPoint演示文稿的幻灯片。我使用这些图表-形式作为较大形式，其具有参数，用户可以选择，以确定哪些是在图表上内的子形式。我们的想法是，用户可确定参数，绘制图表他/她喜欢，并单击一个按钮，它必须与公司的背景模板，PPT幻灯片，等等等等......
所以它的工作原理，但它是我用来实现这个目标的数量方面是非常庞大的。
我使用表达式如下面的：
like forms!frmMain.Month&*
要获得输入值到保存的查询，这是很好，当我第一次开始，但它走过去这么好，他们要这么多的选择，它是推动保存的查询数量/对象了。我需要，因为不同类型的图表数量图表几个保存的表单，我需要有这个能够处理。
所以最后我的问题：
我宁愿做这一切与一些VBA飞。我知道如何插入列表框和文本框的窗体上，我知道如何使用SQL在VBA得到我使用VBA表/查询需要的值，我只是不知道是否有一些VBA我可以使用从所得的记录设定的图表的数据值：
DIM rs AS DAO.Rescordset
DIM db AS DAO.Database
DIM sql AS String
sql = "SELECT TOP 5 Count(tblMain.TransactionID) AS Total, tblMain.Location FROM
tblMain WHERE (((tblMain.Month) = """ & me.txtMonth & """ )) ORDER BY Count
(tblMain.TransactionID) DESC;"
set db = currentDB
set rs = db.OpenRecordSet(sql)
rs.movefirst
some kind of cool code in here to make this recordset
the data of chart in frmChart ("Chart01")
感谢您的帮助。道歉解释的长度。
解决方案
有可能直接在VBA改变数据集作为我已成功地做到这一点。然而，表现也不是那么好，所以我又回到了填充结果临时表和基础图上（见我只问了计算器的问题），但是如果数据集是相当小的，那么你当然可以使它发挥作用。我不在办公室，但如果你想要的代码，我可以张贴在周一
编辑：这里是我使用的旧的代码模块。这是一个完整的东西，但你要寻找的关键部分是对开放图表的数据表，然后改变它的价值这样.cells（1,0）=“獾”的部分。
我enevtly甩这种方法，并用临时表就在我的应用程序的图形是重绘了很多，我需要去的最快的方法给一个“实时”的感觉，但它可能是刚精细您的需求。

其他提示
这样做的一种非常简单的方法是立足于一个查询图表和更新查询，例如：
strSQL = "SELECT ..."
QueryName = "qryByHospital"
If IsNull(DLookup("Name", "MsysObjects", "Name='" & QueryName & "'")) Then
CurrentDb.CreateQueryDef QueryName, strSQL
Else
CurrentDb.QueryDefs(QueryName).SQL = strSQL
End If
DoCmd.OpenReport "rptChartByHospital", acViewPreview
