Excel automatically inserts the graph, but it has no labels. Review the new green "Chart Tools" tab and ribbon at the top of the screen. If you don't see them, click the chart to enable them.

Launch the Excel 2010 spreadsheet that holds the scatter plot you want to adjust. Click anywhere on the chart, then click the "Layout" tab that appears at the top of the Excel window.
