Vertical Line Annotation
Overview
Vertical Line annotation allows to add a vertical line to the chart, as any other annotation it can
be drawn by user or added to the chart via XML or JSON settings. In this article you can learn how
to add a horizontal line via XML or JSON settings and what visual settings can be done.
To learn about basic settings, that can be done with an annotation please
refer to: Drawing Tools and Annotations: General Settings.
Adding annotation via settings
To add a Vertical line annotation to a chart you need to, as with any other annotation, add an annotation node, assign
the id, set "VerticalLine" type and specify the chart id using chart attribute.
In vertical_line_annotation node you need specify time anchor, which defines where line is displayed.
All this you can see in the basic XML/JSON snippet below:
01 |
<?xml version="1.0" encoding="UTF-8"?> |
02 |
< stock xmlns = "http://anychart.com/products/stock/schemas/1.9.0/schema.xsd" > |
05 | id: "idVerticalLineAnnotation1" , |
Live sample below shows a chart with this sample basic Vertical Line annotation:

Visual settings
You have a total control over the look of the Vertical Line, to define its visual settings you
need to add settings node and then use line node to set how it
should look like. Sample XML/JSON snippet below shows this.
If you click on line node in the snippet, XML or JSON reference
will be opened and you will be able to browse all possible settings, including the look of the line in
different states.
