2003 to 2007 Shared Charting
Copying and pasting a Microsoft Office Excel 2003 chart into Microsoft Office PowerPoint 2003 is easy. The real challenge is editing the chart after it's part of your presentation, because the charting tools are different between the applications. With the shared charting engine in the 2007 Microsoft Office system, you can use the same charting tools to create and customize your charts in Microsoft Office Excel 2007, Microsoft Office PowerPoint 2007, and Microsoft Office Word 2007.
