Most charts use some kind of a legend to help readers understand the charted data. Whenever you create a chart in Excel, a legend for the chart is automatically generated at the same time. A chart can be missing a legend if it has been manually removed from the chart, but you can retrieve the missing legend.
This example chart shows a legend explaining the colors for the years 2013, 2014, 2015.
