Bar Charts
Just like pie charts, bar charts can be used to illustrate quantitative differences
between chart elements. They can be used to display the same data a pie chart
displays, but in a different way. One advantage that bar charts have over pie charts is
that the same data for more than one category can be displayed.
For example, suppose we are asked to produce a report comparing the number of
aircraft registered in Washington, DC with the number of aircraft registered in New
York City. Also, the report must illustrate the most popular aircraft models in each
city. If we wanted to display this data graphically via a pie chart, we would have to
create a pie chart for each city. With a bar chart, we can display the whole picture
using a single chart, as can be seen in the following screenshot:
