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 showLegend property is used to set or return the showLegend property. i.e. this property is used to enable or disable the legend of the chart. It accepts boolean type value and the default value is false.

Syntax:

  • It is used to set the showLegend property.
$('Selector').jqxChart({ showLegend : boolean});
  • It is used to return the showLegend property.
var showLegend = $('Selector').jqxChart('showLegend');
