# easyPieChart > Lightweight plugin to render simple, animated and retina optimized pie charts  [](https://travis-ci.org/rendro/easy-pie-chart) [](https://david-dm.org/rendro/easy-pie-chart) [](https://github.com/igrigorik/ga-beacon) ## Features [](http://drbl.in/ezuc) * highly customizable * very easy to implement * resolution independent (retina optimized) * uses `requestAnimationFrame` for smooth animations on modern devices and * works in all modern browsers, even in IE7+ with [excanvas](https://code.google.com/p/explorercanvas/wiki/Instructions) #### framework support * Vanilla JS *(no dependencies)* (~872 bytes) * jQuery plugin (~921 bytes) * Angular Module (~983 bytes) ## Get started #### Installation You can also use [bower](http://bower.io) to install the component: ``` $ bower install jquery.easy-pie-chart ``` #### jQuery To use the easy pie chart plugin you need to load the current version of jQuery (> 1.6.4) and the source of the plugin. ```html ``` #### Vanilla JS If you don't want to use jQuery, implement the Vanilla JS version without any dependencies. ```html ``` #### AngularJS ```html ``` ## Options You can pass these options to the initialize function to set a custom look and feel for the plugin.

Property (Type)	Default	Description
barColor	#ef1e25	The color of the curcular bar. You can either pass a valid css color string, or a function that takes the current percentage as a value and returns a valid css color string.
trackColor	#f2f2f2	The color of the track, or false to disable rendering.
scaleColor	#dfe0e0	The color of the scale lines, false to disable rendering.
scaleLength	5	Length of the scale lines (reduces the radius of the chart).
lineCap	round	Defines how the ending of the bar line looks like. Possible values are: butt, round and square.
lineWidth	3	Width of the chart line in px.
size	110	Size of the pie chart in px. It will always be a square.
rotate	0	Rotation of the complete chart in degrees.
animate	object	Object with time in milliseconds and boolean for an animation of the bar growing ({ duration: 1000, enabled: true }), or false to deactivate animations.
easing	defaultEasing	Easing function or string with the name of a jQuery easing function

## Callbacks All callbacks will only be called if `animate` is not `false`.

Callback(params, ...)	Description
onStart(from, to)	Is called at the start of any animation.
onStep(from, to, currentValue)	Is called during animations providing the current value (the method is scoped to the context of th eplugin, so you can access the DOM element via this.el).
onStop(from, to)	Is called at the end of any animation.

## Plugin api #### jQuery ```javascript $(function() { // instantiate the plugin ... // update $('.chart').data('easyPieChart').update(40); ... // disable animation $('.chart').data('easyPieChart').disableAnimation(); ... // enable animation $('.chart').data('easyPieChart').enableAnimation(); }); ``` #### Vanilla JS ```javascript // 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](http://requirejs.org) you can define your own name. Examples can be found in the `demo/requirejs.html`. ## Browser Support Native support * Chrome * Safari * FireFox * Opera * Internet Explorer 9+ Support for Internet Explorer 7 and 8 with [excanvas](https://code.google.com/p/explorercanvas/wiki/Instructions) polyfill. ## Test To run the test just use the karma adapter of grunt: `grunt test` ## Credits Thanks to [Rafal Bromirski](http://www.paranoida.com/) for designing [this dribble shot](http://drbl.in/ezuc) which inspired me building this plugin. ## Copyright Copyright (c) 2014 Robert Fleischmann, contributors.
