MS Access 2003 - Is there a way to programmatically define data for a chart?

So, I have VBA to create diagrams built using the Form Chart Wizard and automatically insert it into PowerPoint presentation slides. I use these charts as subforms in larger forms that have parameters that the user can select to determine what is on the chart. The idea is that the user can determine the parameter, build a chart to his liking and click on the button and make it on the ppt slide with the company background template, blah blah blah .....

This way it works, although it is very cumbersome in terms of the number of objects that I have to use to achieve this.

I use expressions such as:

like forms!frmMain.Month&*

to get the entered values ​​into saved queries, which was good when I just started, but everything went so well and they need so many options that they give the number of saved queries / objects. I need several saved forms with diagrams due to the number of different types of diagrams that I need to have in order to be able to process.

SO FINALLY TO MY QUESTION:

I would rather do it all on the fly with some VBA. I know how to insert list boxes and text fields on a form, and I know how to use SQL in VBA to get the values ​​I want from tables / queries using VBA, I just don't know if there is any vba that I can use to set the values ​​of chart data from the result set of records:

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")

thank you for your help. apologies for the length of the explanation.
