This is the simplest chart and consists of a continuous line that connects each closing price across every day in the chart.

The exact appearance of the chart will vary depending on which data type is used to plot it.

Select data type

Each symbol's price data is composed of a number of different types of data fields that supply different data for each interval. These data fields, or data types, can include such details as price at last close, price at the market's open, high price of interval, low price of interval, volume of trades, etc.

Line charts can be constructed from only one of a number of data types at one time.

The user selects the type from the Data Field drop-down box:

Select the data field type from the pop-up menu that appears when you change a chart type to line, or in an existing line chart's Parameters tab of its Properties dialog.

The default data type can be altered using the Defaults button of the Properties dialog.

Line Chart Properties

Each chart type has its own chart properties dialog box from which its display properties can be altered by the user.
