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 getItemCoord() method is used to get the coordinates for a data point. It takes the groupIndex, serieIndex, and itemIndex type as parameters of the number type, and returns the coordinates as an object type.
