A line chart displays data values as a set of points connected by a line. You typically use line charts to present large amounts of data that occur over a continuous period of time. A line chart is the most basic type of chart in finance. Figure 8-11 shows an example of a line chart, displaying the value of the Euro against the US Dollar over 10 days.

A line chart is similar to an area chart, except that it does not fill in the area below the line, and it uses a square to mark each data value. There are three subtypes of line charts.
