When you add the same hierarchy to both the Color and Shape drop zones, Pyramid will automatically display the hierarchy's elements in a combined color/ shape legend. While other tools display the attributes across 2 different legends, Pyramid's combined legend enables the report-creator and viewers to easily read and interpret the data, via 1 legend rather than 2.
Examples
In the example below, 2 different hierarchies were added to the Color and Shape drop zones. We can see that 2 different legends are produced accordingly.
However, in this example, 1 hierarchy was added to both the Color and Shape zones, producing a combined color and shape legend. 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:
