If you have an existing Excel chart that you want to use in a PowerPoint, there are more than a couple of ways to get the chart to the slide. We will go over the two simplest ways.
If the chart is exactly as you want it, and you will not ever want to make any changes to it, simply copy the chart from Excel and paste it on your PowerPoint slide. To copy a chart, click on the outer area of the chart page to make it active. Select Copy from the Clipboard section of the Home tab in Excel 2007, from the Edit menu in Excel 2003, or use the Ctrl+C keyboard shortcut in either version. (Right clicking won’t work.) Click on the slide and paste away. The chart will appear as a graphic on your PowerPoint slide.
If you want to use an existing Excel chart in your PowerPoint presentation, but you want the ability to manipulate it, copy the chart just as in the previous step. Don’t paste it onto the slide in the typical fashion, though. In PowerPoint 2007, click on the Paste dropdown button and choose Paste Special. In PowerPoint 2003, Paste Special is on the Edit menu. Select Microsoft Office Excel Worksheet Object and click OK.
To make changes to the chart from PowerPoint, right click it, point to Chart Object and click Open. The chart will open in a datasheet or Excel, allowing you to make the changes you want.
