In technical analysis, a chart that shows a security's price over a period of time, such as a day, a month, or a year. A line chart is constructed by placing points representing the price at different points in time, and then connecting the points with lines. It is useful in showing a security's trend over time. However, it does nothing to indicate the security's high, low, open, or close.

In technical analysis, a chart pattern indicating successive variable stock values over time. For example, a line chart of a stock would display the stock's closing prices over a period of time, connected by a line. Line charts for graphing stock prices are useful if an analyst is interested only in a single value each time. But if high, low, and closing prices all are required, a bar chart is used. Compare point-and-figure chart. See also 200-day moving average.
