A bar graph is a representation of the X- and Y-axes with a series of blocks running

along either the X-axis or the Y-axis that correspond in either height or length
(relatively) to the numerical values listed on the opposing axis that is constructed in

an attempt to illustrate the relationship between the values listed. For example, as

illustrated above, our previous statistical data about rental rates was displayed on a
bar graph during the "multimedia presentation."

Usually bar graphs are shown vertically, but, as the definition implies, they can be
shown horizontally as well. In such a case, the axes switch roles. Instead of the

"information" being listed on the X-axis, it is listed on the Y-axis and the X-axis shows

the "values." In this case, the states are on the Y-axis and the rental vacancy rates are
on the X-axis. Comparisons would then be made by examining the bars' various

"lengths" rather than "heights."

Bar graphs are a good way to compare information from one or many data sets

because you can plot many related data sets on one bar graph. This will prove

valuable in our discussion of pie charts because it is one way that pie charts and bar
graphs differ.
