A Legend in a Chart data region helps a user understand the data plots easily. A legend is connected to the data which is being graphically displayed in the plot area of the chart and is an especially useful tool to analyze data in the case of multiple series.
Several legend types depending on the Chart type are available.
Line plots support all types of legends. Column, Bar, and Area plots support only the Color legend. Scatter plots support Color and Shape legends. Bubble plots support Color and Size, since the shape is circular. The financial charts, on the other hand, do not support any legend series because they do not contain groups.
The color legend displays the match between the plot subsections's fill or stroke color and the corresponding data value subcategories. Almost all types of plot support this legend. See Create Clustered Polar Chart walkthrough.
