Bar graphs are best used to compare the differences between several items at the same time. They are useful in displaying categorical data where each category can be represented by a bar and the length of the bar indicates the value. Bar graphs are also suitable for showing frequency data. Bar graphs are not limited to data that trends upwards and can be used for data that trends downwards as well.
