angular-chart is a AngularJS directive, which is build on top of c3 a d3-based chart library.

Usage

You can get it from Bower:

bower install angular-chart

Add everything to your index.html:

<link rel="stylesheet" href="bower_components/c3/c3.css" />
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css">
<link rel="stylesheet" type="text/css" href="bower_components/angular-circular-navigation/angular-circular-navigation.css">

<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/d3/d3.js"></script>
<script src="bower_components/c3/c3.js"></script>
<script src="bower_components/angular-chart/angular-chart.js"></script>
<script src="bower_components/angular-circular-navigation/angular-circular-navigation.js"></script>

And specify the directive in your module dependencies:

angular.module('myApp', ['angularChart'])

Add the corresponding data in your controller:

$scope.dataset = [
  {
    'day': '2013-01-02_00:00:00',
    'sales': 13461.295202,
    'income': 12365.053
  }
];

$scope.schema = {
  day: {
    type: 'datetime',
    format: '%Y-%m-%d_%H:%M:%S',
    name: 'Date'
  }
};

$scope.options = {
  rows: [{
    key: 'income',
    type: 'bar'
  }, {
    key: 'sales'
  }],
  xAxis: {
    key: 'day',
    displayFormat: '%Y-%m-%d %H:%M:%S'
  }
};

Then you are ready to use the directive in your view:

<div ng-controller="Controller">
