angular-chart.js

Beautiful, reactive, responsive charts for Angular.JS using Chart.js.

Installation

bower

bower install --save angular-chart.js

npm

npm install --save angular-chart.js

cdn

//cdn.jsdelivr.net/angular.chartjs/latest/angular-chart.min.js
//cdn.jsdelivr.net/angular.chartjs/latest/angular-chart.css

manually

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>

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 ([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.

Example

Markup

<canvas id="line" class="chart chart-line" chart-data="data" chart-labels="labels" 
	chart-legend="true" chart-series="series" chart-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);
}]);

AMD RequireJS

See a simple AMD example

CommonJS e.g. webpack

Module should work with CommonJS out of the box e.g. browserify or webpack, see a webpack example.

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 created
update: 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

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.

Browser compatibility

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).
