OLE/ActiveX/.Net in Microsoft Office is great demo-ware, but when you try to use it for real work, it is awfully ‘fiddly.’ I had a problem where I put linked Excel charts into a PowerPoint deck and when I told PowerPoint to refresh the charts from Excel, it refreshed only part of the chart.
I created the links by:
- Going to Excel 2013 and copying the chart.
- Going to PowerPoint 2013, right-clicking, and choosing the Paste Option “Keep Source Formatting & Link Data”.
- This should paste the chart, and apply Excel’s formatting, and use “live” data from the spreadsheet. It uses live data (chart lines) but not chart title or formatting.
- When you paste the chart, it pastes in the current chart title and formatting and it does use them – only after the paste. When you later change the formatting or the chart title, it continues to apply the Excel formatting that was in effect when you pasted the link.
- In other words it amounts to “paste a link to the data” and “apply the current source formatting.”
If this happens to you, you’ll have to re-paste your charts – once – using a different method. After that, your source formatting (including the chart title) will be dynamically updated.
Here’s the magic way to paste/link and get it to do what you want:
- Go to Excel and copy the chart.
- Go to PowerPoint and select the Home tab on the Ribbon.
- Find the Paste button on the ribbon. (I looks like a clipboard. It is still there! I had to look twice for it.)
- Click the drop-down arrow on the Paste button.
- Click the words “Paste special”.
- Choose “Paste link”.
- Choose “Microsoft Excel Chart Object”.
- Press OK.
Related VBA code follows. It is handy to add this to your PowerPoint deck, and then customize the Quick Access Toolbar to add buttons for these subroutines.
