Line Segment


The Line annotation allows you to add a line segment to a chart.

This article explains how to add a Line and configure its basic and visual settings. You can find more settings and other useful information in the articles describing annotations in general:

Basic Settings

To add a Line annotation to a chart, call the line() method of the annotations() object.

Next, use the xAnchor(), valueAnchor(), secondXAnchor(), and secondValueAnchor() methods to set 2 points that determine the position of the line segment. Usually, the most convenient way to do this is object notation:

// create a stock chart
chart = anychart.stock();

// create a plot on the chart
var plot = chart.plot(0);

// access the annotations() object of the plot to work with annotations
var controller = plot.annotations();

// create a Line annotation
    xAnchor: "2006-07-30",
    valueAnchor: 17.24,
    secondXAnchor: "2008-04-06",
    secondValueAnchor: 23.38

This is how it looks like:



The appearance settings of a Line annotation can be configured in three states: normal, hover, and selected. Use the following methods:

Combine them with these methods:

You can also use object notation to specify the settings.

In the sample below, there are two Line annotations with some of the visual settings configured (by using an object in the first case and methods in the second):

// create the first Line annotation and configure its visual settings
var line1 = controller.line({
    xAnchor: "2006-07-30",
    valueAnchor: 17.24,
    secondXAnchor: "2008-04-06",
    secondValueAnchor: 23.38,
    hovered: {stroke: "2 #ff0000"},
    selected: {stroke: "4 #ff0000"}

// create the second Line annotation
var line2 = controller.line();

// set the position of the second annotation
// configure the visual settings of the second annotation
line2.normal().stroke("#006600", 1, "10 2");
line2.hovered().stroke("#00b300", 2, "10 2");
line2.selected().stroke("#00b300", 4, "10 2");
