If desired, you can show (or hide) a legend in the chart. A legend is a small box that shows which data series are displayed in which color/pattern.
To do so, proceed as follows:
Via the "Add chart element" icon
Select the chart and use the ribbon command Chart | Add chart element 
to choose the entry Legend. In the following submenu, you can specify where to position the legend. A check mark in front of it indicates the option which is currently enabled.
You can hide the legend by selecting the entry None.
The entry More takes you to the dialog box with additional options (see below).
Via the dialog box
For additional options, choose the path via the dialog box:
| 1. | Select the chart by clicking on it. |
| 2. | Use the ribbon command Chart | Add chart element to choose the entry Legend and select More in the following submenu to open the dialog box. |
| Alternatively: Select the legend and right-click to open the context menu and select the entry Legend: Properties. |
| 3. | On the Legend tab, specify where the legend should be positioned. If you select the option Custom, the legend can be moved to any position (using the mouse). If you select the option None, the legend will not be displayed. |
Tip: If you choose the entry Chart: Properties via the context menu, the main dialog box for charts opens. You will find the option Legend here also on the Elements tab.
For more information on editing the properties of a legend, see Legend.
