When you add the same hierarchy to both the Color and Shape drop zones, Pyramid will display the hierarchy's elements with a combined color / shape legend.
While other tools display the attributes across two different legends, Pyramid's combined legend enables the report-creator and viewers to easily read and interpret the data, using one legend rather than two.
Combination Legend
Each of the Manufacturers is represented on this line chart with a Color and a Shape. The Legend (highlighted in green below) shows both.

The result is a chart that is easily interpreted and understood, with no need to refer to 2 separate legends for the same elements. Instead, each element is represented in the legend by a single colored shape, exactly as it appears in the chart:
