jQuery

$(function() {
    // instantiate the plugin
    ...
    // update
    $('.chart').data('easyPieChart').update(40);
    ...
    // disable animation
    $('.chart').data('easyPieChart').disableAnimation();
    ...
    // enable animation
    $('.chart').data('easyPieChart').enableAnimation();
});

Vanilla JS

// instantiate the plugin
var chart = new EasyPieChart(element, options);
// update
chart.update(40);
// disable animation
chart.disableAnimation();
// enable animation
chart.enableAnimation();

Using a gradient

new EasyPieChart(element, {
  barColor: function(percent) {
    var ctx = this.renderer.ctx();
    var canvas = this.renderer.canvas();
    var gradient = ctx.createLinearGradient(0,0,canvas.width,0);
        gradient.addColorStop(0, "#ffe57e");
        gradient.addColorStop(1, "#de5900");
    return gradient;
  }
});

AngularJS

For a value binding you need to add the percent attribute and bind it to your controller.

RequireJS

When using RequireJS you can define your own name. Examples can be found in the demo/requirejs.html.
