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

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">
  <angularchart
    dataset="dataset"
    schema="schema"
    options="options">
  </angularchart>
</div>

The Schema is optional, it provides additional information about the dataset. It contains objects for all columns of the dataset that have to specified further. Therefor it provides these keys:

Optional name for the row.

Possible values: datetime, numeric, string

The format is used to specify how the timestamps are saved if they are different to %Y-%m-%dT%H:%M:%S

The following attributes define the chart itself and how to display the data.

Possible Values: json(default), columns, rows

Defines in what orientation the data is saved. Please see C3 Data Examples for examples.

Define a custom limit to stop watching for changes inside the dataset and only watch for changes in the number of items. Default: 100

Defines the columns which should be displayed in the chart. Each row can contain the following:

The column key which identifies the value in each record.

Possible values: line, spline, bar, scatter, area, area-spline, step, area-step, step

Optional name for the row.

Defines if the row should be rendered in the chart.

Defines the color for this row.

Possible values: y, y2

Defines the y axis the row is linked.

Possible values: line, spline, bar, scatter, donut

Defines which kind of chart should be rendered. The value will be the default for rows.type.

When true a selector to switch between multi and pie charts is displayed. Default: false

Defines which column to use and how to display it:

The column key which identifies which value should be shown on the xAxis.

If the xAxis displays a timestamp the format of if can be defined by passing a String which follows the Time Formatting of D3. Alternatively a custom function can be passed. Sample: function (x) { return x.getFullYear(); }

Shows the dropdown to choose which xAxis you want to use. Default: false

Defines yAxis display.

Label displayed for the Y axis

Defines a fixed size of the chart.

A fixed height of the chart.

A fixed width of the chart.

Resize the chart, to a provided size or without parameters to fill the suronding element.

Stacks bar together, like in this example.

Defines the subchart like in this example.

If true a subchart toggle button is displayed.

If true a subchart for zooming is displayed.

Defines the zoom functionality of the chart.

If true it is possible to zoom using the mouse wheel. Default: false

The current zoomed in range can get and set here. Works also for the subchart.

Callback whenever a zoom event is fired. Works also for the subchart.

Defines the legend.

If true a custom legend is displayed. Default: false

If flase the default legend is hidden. Default: true

Defines the annotation lines.

{value: X, text: 'LABEL', axis: 'AXIS'} AXIS can be x, y, y2.

Defines which Items can be selected and are currently selected.

Allows selection of chart elements. Default: false

Allows selection of multiple chart elements if selection is enabled at all. Default: false

Callback whenever a new selection is added.

Callback whenever a selection is removed.

Contains an array with all selected points of the chart:

Multichart (line, spline, bar, scatter):

{
  value: VALUE,
  id: COLUMN_NAME,
  index: X_AXIS_INDEX
}

Pie-, Donut chart: (Currently adding a selection in the Array will not add the selection in the chart)

{
  id: COLUMN_NAME,
  values: [ALL_COLUMN_VALUES]
}

Triggered when you click on a data point. Sample: function(d, element) { console.log('Point at', d.x, 'of the serie', d.name 'has been clicked; corresponding htmlElement:', element) };

Call this function to trigger the c3 resize() function (http://c3js.org/samples/api_resize.html)

We use Karma and jshint to ensure the quality of the code. The easiest way to run these checks is to use grunt:

npm install -g bower grunt-cli
npm install
grunt

Please submit all pull requests the against develop branch. Make sure it passes the CI and add tests to cover your code . Thanks!
