The legend identifies the visual elements used to distinguish different groups of data on the graph. The legend helps you evaluate the effects of grouping. For example, the legend in the preceding graph shows the attributes of the symbols and connect lines used to represent the Control and Education groups.
When you are editing a graph, you can drag the legend or table to a different location. You can also drag a corner or an edge of the legend or table to change its size.
Note, to delete the entire table, just select it and press Delete.
Note, you can only make changes to the labels, not the calculated numeric values.
