This image shows a bar chart twice to indicate the effects of hide and show behavior. In the first instance, the bar chart has two groups of five clustered bars, indicating five data series. The legend shows five series items, each with their respective color indicator.

In the second instance, the chart has only three clustered bars per group, indicating two series have been hidden. The legend has changed the icon for the hidden series, which are now represented by empty squares rather than filled boxes.
