If you create your chart by using the Chart Wizard in Excel, you can include a legend. If you don't include a legend as you create the chart, you can add one later if you need one. To add a legend, follow these steps:

1. Activate the chart.

2. Choose the Chart, Chart Options menu command. You can also right-click the border area of the chart and select Chart Options from the shortcut menu.

Excel displays its Chart Options dialog box.

3. Click the Legend tab.

4. Select the Show Legend check box.

5. Select a placement option for the legend by clicking the appropriate radio button: Bottom, Corner, Top, Right, or Left.

The picture of the chart in the Legend tab displays how the legend appears on the chart for various placement options.

6. Click OK.
