Line Chart - Basic Operations

A line chart displays a set of data by drawing a data point for each datum and drawing a line that connects all the data points in sequence. The vertical position of a data point is determined by the value of the associated datum. The horizontal position of a data point is determined by the order of the associated datum in the data set.

A line chart can display up to 8 sets of data. The following example shows a line chart that displays 3 sets of data.

A line chart can provide a cursor for you to select desired data points. The cursor of the line chart is a vertical line segment. The user can move the cursor horizontally within a line chart to the desired data point(s). The values of the selected data points can be displayed and output to an internal variable called Cursor Data Receiving Buffer.

A line chart can be displayed in vertical direction with transparent background.

You can complete all the settings of a line chart in the Line Chart dialog box. This dialog box contains the following four pages.
