Infinite Line


The Infinite Line annotation allows to add an infinite line to a chart.

This article explains how to add an Infinite 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 an Infinite Line annotation to a chart, call the infiniteLine() method of the annotations() object.

Next, use the xAnchor(), valueAnchor(), secondXAnchor(), and secondValueAnchor() methods to set 2 points that determine the position of the infinite line. 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 an Infinite Line annotation
    xAnchor: "2006-07-30",
    valueAnchor: 17.24,
    secondXAnchor: "2008-04-27",
    secondValueAnchor: 26.75

This is how it looks like:

Visual Settings

You can also configure the visual settings of an Infinite Line annotation:

In the sample below, there are two Infinite 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 Infinite Line annotation and configure its visual settings
infiniteLine1 = controller.infiniteLine({
    xAnchor: "2006-07-30",
    valueAnchor: 17.24,
    secondXAnchor: "2008-04-27",
    secondValueAnchor: 26.75,
    hoverStroke: "2 #FF0000",
    selectStroke: "5 #FF0000"

// create the second Infinite Line annotation
infiniteLine2 = controller.infiniteLine();

// set the position of the second annotation
// configure the visual settings of the second annotation
infiniteLine2.stroke("#2196F3", 3, "10 2");
