There are many types of graphs used in statistics.
Bar graphs are an excellent way to show results that are one time, that aren't continuous - especially samplings such as surveys, inventories, etc.
A bar chart is marked off with a series of lines called grid lines. These lines typically mark off a numerical point in the series of numbers on the axis or line. However, too many grid lines can make it confusing.
Bar graphs are useful to get an overall idea of trends in responses - which categories get many versus few responses.

A bar graph represents different data between two things. It can represent growth or decrease over a period of time.

Um, data?
A bar graph uses vertical or horizontal bars to represent the relationship between data. The higher/longer the bar, the relatively larger the data.

Bar graphs are a very common type of graph best suited for a qualitative independent variable. Since there is no uniform distance between levels of a qualitative variable, the discrete nature of the individual bars are well suited for this type of independent variable. Though you can extract trends between bars (e.g., they are gradually getting longer or shorter), you cannot calculate a slope from the heights of the bars.
