A style of chart used by some technical analysts, on which, as illustrated below, the top of the vertical line indicates the highest price a security traded at during the day, and the bottom represents the lowest price. The closing price is displayed on the right side of the bar, and the opening price is shown on the left side of the bar. A single bar like the one below represents one day of trading.

Example of a bar chart

A bar chart or bar graph is a chart with rectangular bars with lengths proportional to the values that they represent. Bar charts are used for comparing two or more values that were taken over time or on different conditions, usually on small data sets. The bars can be horizontally oriented (also called bar chart) or vertically oriented (also called column chart). Sometimes a stretched graphic is used instead of a solid bar. It is a visual display used to compare the amount or frequency of occurrence of different characteristics of data and it is used to compare groups of data.

This bar chart shows both the results of 2004, and those of 1999:
