If you paste the chart with a link, the original data and the original chart are still sitting in the Excel file. This is a good choice if the data is historical and you see little need to update in the future. If you paste the chart as a picture, you are establishing no connection between the underlying data and the pasted chart. These choices are available by clicking the drop-down arrow next to the paste icon at the lower right corner of the pasted chart: Paste Options Each of those impacts your ability to update the chart.
Assuming the chart was created in Excel and then copied in preparation for adding it to the slide, there are basically three different ways to paste the chart – embedding the chart, linking the chart, and pasting the chart as a picture. The first part of the updating answer lies in how the chart was added to the slide. But what if the chart data change? How do we update the slide?
So the combination of an Excel chart on a PowerPoint slide is a powerful way to get a point across. Excel Charts are prime examples of the old saying “A picture is worth a thousand words,” and PowerPoint presentations provide a great vehicle for passing a chart’s message on to an audience.
