I have also taken a look at your site (PeltierTech Excel/XL_PPT) to align the arrays/charts in the middle of the PPT presentation. This is very helpful!
The following script works perfectly fine, but I need to adjust it to my needs somehow:

' Align pasted chart
PPApp.ActiveWindow.Selection.ShapeRange.Align msoAlignCenters, True
PPApp.ActiveWindow.Selection.ShapeRange.Align msoAlignMiddles, True

Do you have any tips on this point since I work with arrays instead of copy-pasting the chart(s)?

Yours sincerely,

Djani
