I have an Excel file with map charts to monitor wildfires from a national database. I create maps of e.g. number of fires per administrative region, for different years. I insert the map for say 2019 in PowerPoint for a presentation, and I go to file>info>Edit-links-to-files>break-link, so that the map doesn't change when i chose 2020 in the original excel file.
That works for other types of charts, but the map-charts keep refreshing, even after breaking the link. I've also tried a paste special as a "Microsoft Office Graphic Object", and breaking the link, but no sucess. I could paste as a picture of course, but I need other people in my organization to be able to change e.g. color scale, labels, etc.
I didn't find any reference to that issue, someone is experiencing the same ? Any solution ? Thanks a lot !
