Questions tagged [bar-chart]

A bar chart is graphical representation of data where the value is represented by the length of the bar.

In contrast, some examples of continuous data would be 'height' or 'weight'. A bar chart is very useful for recording certain information whether it is continuous or not continuous data. Bar charts also look a lot like histograms. They are often mistaken for each other.

Example of a bar chart, with 'Country' as the discrete data set.
