angular-chart 
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 --saveAdd everything to your index.html:
<link rel="stylesheet" href="bower_components/c3/c3.css" />
<link rel="stylesheet" href="bower_components/angular-chart/angular-chart.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>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>Schema
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:
name : String
Optional name for the row.

xAxis.key : String (see example)
The column key which identifies which value should be shown on the xAxis.
xAxis.displayFormat : String | Function (see example)
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(); }

yAxis.min : String (see example)
Lets you define the range for the Y axis
yAxis.max : String (see example)
Lets you define the range for the Y axis
yAxis.displayFormat : function
Set the tick format Y axis e.g. yAxis.displayFormat = d3.format(".0%") to get a percentage format. A reference of all d3 format functions can be found here
y2Axis : Object
Defines y2Axis display.
y2Axis.label : String
Label displayed for the Y2 axis
y2Axis.min : String
Lets you define the range for the Y2 axis
y2Axis.max : String
Lets you define the range for the Y2 axis
yAxis.displayFormat : function
Set the tick format Y2 axis e.g. y2Axis.displayFormat = d3.format(".0%") to get a percentage format. A reference of all d3 format functions can be found here
size : Object
Defines a fixed size of the chart.

size.width : Int (see example)
A fixed width of the chart.
groups : Array
Stacks bar together, like in this example.
subchart : Object
Defines the subchart like in this example.
subchart.selector : boolean (see example)
If true a subchart toggle button is displayed.
subchart.show : boolean (see example)
If true a subchart for zooming is displayed.
zoom : Object
Defines the zoom functionality of the chart.
zoom.enable : boolean (see example)
If true it is possible to zoom using the mouse wheel. Default: false
zoom.range : Array [a, b] (see example)
The current zoomed in range can get and set here. Works also for the subchart.
zoom.onzoom : function
Callback whenever a zoom event is fired. Works also for the subchart.
tooltip : Object
Defines the tooltip.
tooltip.displayFormat : function
Defines the format for the numbers in the tooltip. e.g. tooltip.displayFormat = d3.format(".0%") to get a percentage format. A reference of all d3 format functions can be found here

selection.selected : Array
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]
}
onclick : function
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) };
resize : function
Call this function to trigger the c3 resize() function (http://c3js.org/samples/api_resize.html)
Development 
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
gruntContributing
Please submit all pull requests the against develop branch. Make sure it passes the CI
