Zoom Controls

Overview

Zoom Control Panel is an HTML object with three buttons: Zoom All (100%, or 1x Zoom), Zoom In and Zoom Out. To create a Zoom Control Panel use the zoom() method.

Modules

Zoom controls require the Common UI module:

<script src="https://cdn.anychart.com/releases/v8/js/anychart-ui.min.js"></script>  

Also, you should reference the anychart-ui.min.css and anychart-font.min.css files:

<link rel="stylesheet" type="text/css" href="https://cdn.anychart.com/releases/v8/css/anychart-ui.min.css"/>
<link rel="stylesheet" type="text/css" href="https://cdn.anychart.com/releases/v8/fonts/css/anychart-font.min.css"/>

Enabling

There is a new layer created for the Zoom Control Panel over the chart layer. The target() method is necessary to set the target map for the zooming panel, and the render() method provides the Zoom Controls Panel rendering.

var zoomController = anychart.ui.zoom();
zoomController.target(map);
zoomController.render();
