Adding Markers

A marker is a vertical or horizontal line drawn on top of the chart. Markers are used to identify a particular data point or chart coordinate. A programmer can write code that moves markers as you move the mouse, or displays a marker when you click on part of a chart. You can set where to display X- or Y-markers, and customize their visual attributes.

The chart can have two markers, X and Y. Each marker has positioning and LineStyle attributes that you can customize.
