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. The 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 removeColorScheme() method is used to remove the color scheme by name. It takes scheme type value as parameter, takes String type value and does not return any value.
Syntax:
var removeColorScheme= $('#jqxChart')
.jqxChart('removeColorScheme', string);
