angular-chart
adjustable dynamically updating stateful charts for AngularJS
angular-chart is a AngularJS directive, which is build on top of C3.js a d3-based chart library.
Install
You can download all necessary angular-chart files manually or install them with Bower:
bower install angular-chart --save
Add everything to your index.html:
<link rel="stylesheet" href="bower_components/c3/c3.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>
Specify the directive in your module dependencies:
angular.module('myApp', ['angularChart'])
Usage
Add the corresponding data in your controller:
angular
.module('myApp')
.controller('Controller', function($scope) {
$scope.options = {
data: [
{
sales: 130,
income: 250
}
],
dimensions: {
sales: {
type: 'bar'
},
income: {
axis: 'y2'
}
}
};
// optional (direct access to c3js API http://c3js.org/reference.html#api)
$scope.instance = null;
});
Then you are ready to use the directive in your view:
<div ng-controller="Controller">
<angular-chart options="options" instance="instance"></angular-chart>
</div>

OPTIONS
The options object can contain four different keys:
data
JSON based data you want to visualizedimensions
Specifies which and how the data dimensions will be plottedchart
Access to the full API of C3.js to style your visualizationstate
Current state of interactions with the chart
data
A JSON data array which can contain numbers and string.
$scope.options = {
data: [
{
sales: 130,
weekday: 'Monday',
date: '2015-04-04 12:13:55'
}
]
};
dimensions
Specifies which and how the data dimensions will be plotted.
dimension.type : String
Possible values: line, spline, bar, scatter, area, area-spline, step, area-step, step
--
dimension.axis : String
Possible values: x, y, y2
Defines the axis the row is linked.
--
dimension.name : String
Optional name for the row.
--
dimension.show : String
Defines if the row should be rendered in the chart.
--
dimension.color : String
Defines the color for this row.
--
dimension.label : boolean
Defines if data labels inside the chart are shown or not (default: false
). To define axis labels specify chart.axis.y.label.
--
dimension.dataType : String
Possible values: numeric, indexed, category, datetime
--
dimension.dataFormat : String | Function
The dataFormat is used convert timestamps in in Date objects, it uses the D3 Time Formatting. Sample:%Y-%m-%dT%H:%M:%S
--
dimension.displayFormat : String | Function
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(); }
--
dimension.prefix : String
To specify the appearance of your data in tooltips, labels and in the axis ticks you can add a prefix. Sample: $
--
dimension.postfix : String
To specify the appearance of your data in tooltips, labels and in the axis ticks you can add a postfix. Sample: €
chart
Access to the full API of C3.js to customize your visualization.
chart.data.watchLimit
The watchLimit
key is added in addition to the c3-API. Add a custom limit to define when to stop watching for changes inside of data and only watch for changes in the number of items the data array contains. Default: 100
state
Current state of interactions with the chart.
state.range : Array [a, b]
The current zoomed in range can get and set here. Works also for the subchart.
--
state.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]
}
INSTANCE
The instance
attribute of the directive will be filled with a promise on initialization. The promise will be fulfilled the first time the chart is generated. Every time a new chart instance is created the instance
of the directive will be updated as well.
You can call all c3js API calls such as flow()
, resize()
, ... on the chart instance.
Events
The angular-chart-rendered
event is emitted every time a chart is generated or regenerated. It gives access to the options
the chart is generated with and to the newly created chart instance.
$scope.$on('angular-chart-rendered', function(event, options, instance) {
console.log(options, instance);
});
custom Style
The whole chart is based on SVG, which allows you to stlye most parts using CSS. The documentation of c3.js provides a few examples on how to style your chart.
Upgrade 0.2.x to 0.3.0
<angular-chart></angular-chart>
should be used instead of<angularchart></angularchart>
- the
dataset
now lives inside the options you pass to angular-chart:
// old
$scope.dataset = [...];
$scope.options = {};
// new
$scope.options = {
data: [...],
dimensions: {},
chart: {},
state: {}
};
- integrate the
schema
object into thedimensions
:
// old
$scope.schema = {
day: {
type: 'datetime',
format: '%Y-%m-%d_%H:%M:%S',
name: 'Date'
}
};
// new
$scope.options = {
dimensions: {
day: {
dataType: 'datetime',
dataFormat: '%Y-%m-%d_%H:%M:%S',
name: 'Date'
}
}
};
- the
options.rows
andoptions.xAxis
are now integrated in thedimensions
:
// old
$scope.options = {
rows: [{
key: 'income',
type: 'bar'
}, {
key: 'sales'
}],
xAxis: {
key: 'day',
displayFormat: '%Y-%m-%d %H:%M:%S'
}
};
// new
$scope.options = {
dimensions: {
income: {
axis: 'y',
type: 'bar'
},
sales: { // all visible dimensions have to be defined here
}, // leave the object empty to add a line to the y-Axis
day: {
axis: 'x',
displayFormat: '%Y-%m-%d %H:%M:%S'
}
}
};
data.watchLimit
can now be set atoptions.chart.data.watchLimit
data.orientation
is currently not supported, please stick to json data- the in-place editor features
typeSelector
,xAxis.selector
,subchart.selector
andlegend.selector
are no longer part of the main project. An additional plugin will make them available again soon.
Development
We use Karma and jshint to ensure the quality of the code. The easiest way to run these checks is to use gulp:
npm install -g bower gulp
npm install
bower install
gulp

Contributing
Please submit all pull requests the against master branch. Make sure it passes the CI and add tests to cover your code . Thanks!
Bug reports
A bug is a demonstrable problem that is caused by the code in the repository. Good bug reports are extremely helpful - thank you!
Guidelines for bug reports:
-
Use the GitHub issue search — check if the issue has already been reported.
-
Check if the issue has been fixed — try to reproduce it using the latest
master
branch in the repository. -
Isolate the problem — create a reduced test case in a live example. Please use this plunker to add your configuration which create the bug.
A good bug report shouldn't leave others needing to chase you up for more information. Please try to be as detailed as possible in your report. What is your environment? What steps will reproduce the issue? What browser(s) and OS experience the problem? What would you expect to be the outcome? All these details will help people to fix any potential bugs.
Example:
Short and descriptive example bug report title
A summary of the issue and the browser/OS environment in which it occurs. If suitable, include the steps required to reproduce the bug.
- This is the first step
- This is the second step
- Further steps, etc.
<url>
- a link to the reduced test caseAny other information you want to share that is relevant to the issue being reported. This might include the lines of code that you have identified as causing the bug, and potential solutions (and your opinions on their merits).
