A bar chart displays price changes within a specified period of time. This chart consists of several bars, each of which alone represents the four prices during a specified time period: initial (open), maximum (high), minimum (low), and final prices (close). Analysts use this information to analyze short term and long term market trends. In a bar chart, like many of the price charts, the vertical axis (Y) represents the price scale and the horizontal axis (X) represents the time scale.
