Thanks Joel, I was able to access the excel sheet this way. However, what I
wanted to do was either not possible, or needs a lot more work.
In short, I have a range of data and the chart pasted on the same slide.
Being a highly optimistic fellow, I was hoping that when I change the data,
the chart will be updated (as they are linked in the original workbook).
Silly me.
I think I am going to try again by pasting them as links, then change data
in thesource file and update links. This ought to work I guess, if can figure
out how to open the source invisibly and update links during presentation
show.
Thanks for the tip though.

I assume you used PasteSpecial to put the chart into Power Point as an
excel object so the chart is an ActiveX object.
1) When using one office product in another office product you need to
add the reference library to the VBA application to be able to use all
the commands.
From Power Point VBA menu
Tools - References - Microsoft Excel XX.X objct Library
Make sure you check the box next to the objet and press the OK button
2) Here is some code to get you started.
Sub test()
Dim Excelbk As Excel.Workbook
Dim Excelchart As Excel.Chart
Set Myslide = ActivePresentation.Slides(1)
For Each myshape In Myslide.Shapes
Set Excelbk = myshape.OLEFormat.Object
Set Excelchart = Excelbk.ActiveChart
Next myshape
End Sub
If you get an error in the above code verify the Reference is checked
in the VBA menu.
Once you have the excel chart you should be able to use the object like
any excel chart. Chart are hard objects to work with and should refer
to a specific forum on excel charts for help. I've done a good number
of macros using excel charts and still have trouble get the exact
syntax. I usually refer back to one of my old macros for charting when
I run into problems.
