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.
You can download all necessary angular-chart files manually or install them with Bower:
bower install angular-chart --saveAdd 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'])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'
}
}
};
});Then you are ready to use the directive in your view:
<div ng-controller="Controller">
<angular-chart options="options"></angular-chart>
</div>learn how to upgrade from v0.2.x
The options object can contain four different keys:
dataJSON based data you want to visualizedimensionsSpecifies which and how the data dimensions will be plottedchartAccess to the full API of C3.js to style your visualizationstateCurrent state of interactions with the chart
A JSON data array which can contain numbers and string.
$scope.options = {
data: [
{
sales: 130,
weekday: 'Monday',
date: '2015-04-04 12:13:55'
}
]
};Specifies which and how the data dimensions will be plotted.
Possible values: line, spline, bar, scatter, area, area-spline, step, area-step, step
--
Possible values: x, y, y2
Defines the axis the row is linked.
--
Optional name for the row.
--
Defines if the row should be rendered in the chart.
--
Defines the color for this row.
--
Defines if data labels inside the chart are shown or not (default: false).
To define axis labels specify chart.axis.y.label.
--
Possible values: numeric, indexed, category, datetime
--
The dataFormat is used convert timestamps in in Date objects, it uses the D3 Time Formatting.
Sample:%Y-%m-%dT%H:%M:%S
--
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(); }
--
To specify the appearance of your data in tooltips, labels and in the axis ticks you can add a prefix.
Sample: $
--
To specify the appearance of your data in tooltips, labels and in the axis ticks you can add a postfix.
Sample: €
Access to the full API of C3.js to customize your visualization.
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
Current state of interactions with the chart.
The current zoomed in range can get and set here. Works also for the subchart.
--
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]
}
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.
<angular-chart></angular-chart>should be used instead of<angularchart></angularchart>- the
datasetnow lives inside the options you pass to angular-chart:
// old
$scope.dataset = [...];
$scope.options = {};
// new
$scope.options = {
data: [...],
dimensions: {},
chart: {},
state: {}
};- integrate the
schemaobject 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.rowsandoptions.xAxisare 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.watchLimitcan now be set atoptions.chart.data.watchLimitdata.orientationis currently not supported, please stick to json data- the in-place editor features
typeSelector,xAxis.selector,subchart.selectorandlegend.selectorare no longer part of the main project. An additional plugin will make them available again soon.
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

angular-chart was first developed as the technical part of my bachelor thesis "Real-time collaborative Visual Analytics with AngularJS and D3.js". The thesis was written at the Professorship of Media Computer Science (Prof. Dr. Michael Granitzer) of the University of Passau and in cooperation with ONE LOGIC.
