jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful and optimized framework, platform-independent, and widely supported. jqxChart is a lightweight and powerful chart widget written 100% in JavaScript. It offers many advanced features and supports three different rendering technologies – SVG, HTML5 Canvas & VML.

The getXAxisRect() method is used to get the rectangle coordinates of the x-axis. It takes a single number type value groupIndex as the parameter and returns an object that contains the data of the rectangle.

Syntax:

var getXAxisRect = chartInstance.getXAxisRect(0);
