Using a slicer in Excel, I am cycling through various categories and copy-pasting charts to a PowerPoint presentation. Unfortunately as soon as I switch the category, the copy-pasted chart updates in PowerPoint.
I was able to overcome this issue previously by using a virtual machine and running Excel in said virtual machine. If copy & pasted that way, the charts in PowerPoint wouldn't automatically update subsequently. However I don't have access to this particular workaround anymore. The update properties for linked data files in PowerPoint are set to manual and update automatically is unchecked.
Pasting as an image is not an option because there is always a chance that someone who is looking at that presentation might want to make some last-minute changes to the chart. (i.e. Changing the wording of chart titles or something like that)
