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 grayscale property is used to set or return the grayscale property. i.e. this property is used to display the scale in gray color. It accepts boolean type value and its default value is false.

Syntax:

Set the grayscale property.

$('Selector').jqxChart({ grayScale : boolean});

Return the grayscale property.

var grayScale = $('Selector').jqxChart('grayScale');
