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 getValueAxisRect() method is used to get the rectangle coordinates of the value axis. It takes groupIndex type value as parameter, number type value, and return object type value.
Syntax:
var getValueAxisRect= chartInstance.getValueAxisRect(0);
