jQWidgets jqxChart getColorScheme() Method

  • Last Updated : 15 Nov, 2021

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 getColorScheme() method is used to get the colors of a color scheme by name. It takes schemeName type value as a parameter, takes String type value, and returns array type value.

Syntax:

var getColorScheme = $('#jqxChart')
    .jqxChart('getColorScheme', string);
