PowerPoint charts let you communicate data graphically. Use charts in PowerPoint to help see the meaning behind the numbers.
PowerPoint uses a spreadsheet as a placeholder for entering chart data, much like Excel. The process of entering data is fairly simple, but if you are unfamiliar with Excel you might want to review our Excel 2013 Cell Basics lesson.
You can edit the chart data at any time by selecting your chart and clicking the Edit Data command on the Design tab.
You can also click the Insert Chart command in a placeholder to insert a new chart.
If you already have data in an existing Excel file you want to use for a chart, you can transfer the data by copying and pasting it. Just open the spreadsheet in Excel, select and copy the desired data, and paste it into the source data area for your chart.
You can also embed an existing Excel chart into your PowerPoint presentation. This may be useful when you know you'll need to update the data in your Excel file and want the chart to automatically update whenever the Excel data is changed.
