If that is the case, then it would be very helpful to see the source data so that I may have something to test on my end rather than guessing pieces of code that may or may not work for your case.

If you could attach a sample of your workbook by replying, click "Go Advanced" and click the paperclip attachment icon to directly upload a workbook. If your document contains sensitive data, create a similar one with made up data. Just make sure that the number of graphs and their locations match your source file.

From there, I can take a look at getting a working macro.

It would be extremely helpful if you could attach an example of the result you expect as well for your powerpoint presentation. This way, we have the starting point and the end point to compare it to. You'll get a much better response from this forum in the future if you give a very clear idea of the results you would like in addition to the source information.
