A key can make it easier to interpret the data sets that each part of the graph represents, especially if there is no room in the graph area for labels.
The line and the bar graph is used to describe a graph that compares two sets of data.

Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
The difference between a bar graph and a double bar graph is...... A bar graph displays one set of data, and a double bar graph compares two different sets of information/data.So should have a key.

Two sets A and B are said to be comparable if and only if either 'A is a subset of B' or 'B is a subset of A'.
