Question : General MS Graph problems in Access 2007

I have an app built in Access 2007.  At one point, I have an MS Graph object on a sub form.  I set the row source type as "Table/Query" and the row source as a SQL query against a local table.  The make-up of the query depends on the objective to be shown in the graph.

Depending upon my needs, I change the graph type from XY Scatter to Bubble Chart as needed and coordinate the query to support the type.

Frequently, but for no reason I have been able to determine, even though I have proper data in the Datasheet as a result of the query, the graph seems to be "disconnected" from the datasheet.

I have been having a long discussion in
http://www.experts-exchange.com/Microsoft/Development/MS_Access/Access_Forms/Q_25001927.html?cid=1575#a26128011
but now must close that out.  Based on help I got there, I know I have the correct organization of data in my datasheet for an XY Scatter (X,Y,S).  Here is a sample:
Business_Score      Technical_Score      Application_Name
2.724206      2.748611      AAAAA
3.425397      3.417583      BBBBB
3.32619      3.274214      CCCCC
3.452381      3.372123      DDDDD
3.04881      3.363636      EEEEE
3.225397      3.363636      FFFFF
3.68718      3.542456      GGGGG
3.971825      2.971705      HHHHH
4.360714      3.276933      IIIII
There are actually 86 rows in the datasheet.  Every cell that should be filled is.

But, when I look at the graph, there are only 5 points plotted, none of which relate to any of the values in the datasheet.

At other times, when I set the row source query to produce data for a Bubble Chart, and then try to change the chart type to Bubble Chart, I either get a message saying I must have 2 or more points to plot before I can change it to Bubble Chart (there are 86 in the datasheet) or I get an object error.  Then, still other times, it works as expected.

I have compacted and repaired the accdb numerous times, and have built a new accdb and imported all components.  This problems comes and goes.

How does this "disconnect" happen and more importatnly what steps can I take to prevent it?  I must be able to control this so my users do not run into it.

Well, it looks as though you don't need me any more! Good job!

Changing a property of a collection is often implemented internally as a loop. It should be slightly faster than changing the same property element by element, because refresh issues should be optimised, but that isn't always the case.

However, for Bubble charts, there is global size option affecting all bubbles in all series.
