Horizontal Range

Overview

The Horizontal Range annotation allows you to add a horizontal range/channel to a chart.

This article explains how to add a Horizontal Range 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 Horizontal Range annotation to a chart, call the horizontalRange() method of the annotations() object.

Next, use the valueAnchor(), secondValueAnchor() methods to set 2 points that determine the position of the horizontal channel. 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 Horizontal Channel annotation
controller.horizontalRange({
    valueAnchor: 28.92,
    secondValueAnchor: 33.13,
});

This is how it looks like:

Appearance

The appearance settings of a Horizontal Channel 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 Horizontal Channel annotations with some of the visual settings configured (by using an object in the first case and methods in the second):

// create the first Horizontal Channel annotation and configure its visual settings
var horizontalChannel1 = controller.horizontalRange({
    valueAnchor: 28.92,
    secondValueAnchor: 33.13,
    hovered: {
        fill: "#398cae 0.3",
        stroke: "2 #ff0000"
    },
    selected: {
        fill: "#398cae 0.3",
        hatchFill: "forward-diagonal",
        stroke: "4 #ff0000"
    }
});

// create the second Horizontal Channel annotation
var horizontalChannel2 = controller.horizontalRange();

// set the position of the second annotation
horizontalChannel2.valueAnchor(29.13);
horizontalChannel2.secondValueAnchor(17.87);

// configure the visual settings of the second annotation
horizontalChannel2.normal().fill("none");
horizontalChannel2.normal().stroke("#006600", 1, "10 2");
horizontalChannel2.hovered().stroke("#00b300", 2, "10 2");
horizontalChannel2.selected().stroke("#00b300", 4, "10 2");
