angular-chart.js
Beautiful, reactive, responsive charts for Angular.JS using Chart.js.
Installation
bower install angular-chart.js --save
or copy the files from dist/
. Then add the sources to your code (adjust paths as needed) after
adding the dependencies for Angular and Chart.js first:
<script src="../bower_components/angular/angular.min.js"></script>
<script src="/bower_components/Chart.js/Chart.min.js"></script>
<script src="/bower_components/angular-chart.js/dist/angular-chart.js"></script>
Utilisation
There are 6 types of charts so 6 directives: chart-line
, chart-bar
, chart-radar
, chart-pie
,
chart-polar-area
, chart-doughnut
.
They all use mostly the same API:
data
: series datalabels
: x axis labels (line, bar, radar) or series labels (pie, doughnut, polar area)options
: chart options (as from Chart.js documentation)series
: (default:[]
): series labels (line, bar, radar)colours
: data colours (will use default colours if not specified)getColour
: function that returns a colour in case there are not enough (will use random colours if not specified)click
: onclick event handlerhover
: onmousemove event handlerlegend
: (default:false
): show legend below the chart
There is another directive chart-base
that takes an extra attribute chart-type
to define the type
dynamically, see stacked bar example.
Browser compatibility
For IE8 and older browsers, you will need to include excanvas. You will also need shims for ES5 functions.
<head>
<!--[if lt IE 9]><script src="excanvas.js"></script><![endif]-->
<!--[if lt IE 9]><script src="es5-shim.js"></script><![endif]-->
</head>
Example
Markup
<canvas id="line" class="chart chart-line" data="data" labels="labels"
legend="true" series="series" click="onClick"></canvas>
Javascript
angular.module("app", ["chart.js"])
// Optional configuration
.config(['ChartJsProvider', function (ChartJsProvider) {
// Configure all charts
ChartJsProvider.setOptions({
colours: ['#FF5252', '#FF8A80'],
responsive: false
});
// Configure all line charts
ChartJsProvider.setOptions('Line', {
datasetFill: false
});
}])
.controller("LineCtrl", ['$scope', '$timeout', function ($scope, $timeout) {
$scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
$scope.series = ['Series A', 'Series B'];
$scope.data = [
[65, 59, 80, 81, 56, 55, 40],
[28, 48, 40, 19, 86, 27, 90]
];
$scope.onClick = function (points, evt) {
console.log(points, evt);
};
// Simulate async data update
$timeout(function () {
$scope.data = [
[28, 48, 40, 19, 86, 27, 90],
[65, 59, 80, 81, 56, 55, 40]
];
}, 3000);
}]);
Reactive
angular-chart.js watch updates on data, series, labels, colours and options and will update, or destroy and recreate, the chart on changes.
Events
angular-chart.js emits the following events on the scope
and pass the chart as argument:
create
: when chart is createdupdate
: when chart is updated
$scope.$on('create', function (event, chart) {
console.log(chart);
});
Note: the event can be emitted multiple times for each chart as the chart can be destroyed and
created multiple times during angular watch
lifecycle.
angular-chart.js listen to the scope destroy
event and destroy the chart when it happens.
Colours
There are a set of 7 default colours. Colours can be replaced using the colours
attribute.
If there is more data than colours, colours are generated randomly or can be provided
via a function through the getColour
attribute.
Hex colours are converted to Chart.js colours automatically, including different shades for highlight, fill, stroke, etc.
Issues
Issues or feature requests for Chart.js (e.g. new chart type, new axis, etc.) need to be opened on Chart.js issues tracker
Please check if issue exists and otherwise open issue in github. Please add a link to a plunker, jsbin, or equivalent. Here is a jsbin template for convenience.
