Charts in PowerPoint can be customized by changing the appearance of various chart elements. Typically, the legend is a box or area that contains color or pattern swatches representing the series in a chart. The legend is the box that captions the series: Series 1, Series 2, and Series 3 and identifies them with different colors so that you can follow which series each of the columns in that chart represent.
