Beautiful, reactive, responsive charts for Angular.JS using Chart.js.
If you are interested by the upcoming 2.0 version of Chart.js, please checkout the chartjs-2.0 branch. Report issues and feedback for this version by opening issues prefixed by "chartjs-2.0" in the title.
See jtblin#123 for more details and subscribe to it to get the latest progress on Chart.js 2.0 integration.
bower install --save angular-chart.js
npm install --save angular-chart.js
//cdn.jsdelivr.net/angular.chartjs/latest/angular-chart.min.js
//cdn.jsdelivr.net/angular.chartjs/latest/angular-chart.css
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:
<head>
<link rel="stylesheet" href="bower_components/angular-chart.js/dist/angular-chart.css" />
<head>
<body>
...
</body>
<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.min.js"></script>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 ([chart-] indicates an optional but recommended prefix):
[chart-]data: series data[chart-]labels: x axis labels (line, bar, radar) or series labels (pie, doughnut, polar area)[chart-]options: chart options (as from Chart.js documentation)[chart-]series: (default:[]): series labels (line, bar, radar)[chart-]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)[chart-]click: onclick event handler[chart-]hover: onmousemove event handler[chart-]legend: (default:false): show legend below the chart
DEPRECATION WARNING: Note that all attributes which do not use the [chart-] prefix are deprecated
and may be removed in a future version.
There is another directive chart-base that takes an extra attribute chart-type to define the type
dynamically, see stacked bar example.
<canvas id="line" class="chart chart-line" chart-data="data" chart-labels="labels"
chart-legend="true" chart-series="series" chart-click="onClick"></canvas> 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);
}]);Module should work with CommonJS out of the box e.g. browserify or webpack, see a webpack example.
angular-chart.js watch updates on data, series, labels, colours and options and will update, or destroy and recreate, the chart on changes.
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.
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 or feature requests for Chart.js (e.g. new chart type, new axis, etc.) need to be opened on Chart.js issues tracker
For general questions about usage, please use http://stackoverflow.com/
Please check if issue exists first, otherwise open issue in github. Ensure you add a link to a plunker, jsbin, or equivalent. Here is a jsbin template for convenience.
For IE8 and older browsers, you will need to include excanvas. You will also need a shim for ES5 functions.
You also need to have height and width attributes for the <canvas> tag of your chart if using IE8 and older browsers. If you do not have these attributes, you will need a
getComputedStyle shim and the line document.defaultView = window;, but there still may be errors (due to code in Chart.js).
