Angular Chartjs Doughnut Directive

This directive let you use a chartjs doughnut thanks to an AngularJS directive.

Requirements

Load Chart.js and this directive with the following code:

<script type="text/javascript" src="Chart.js"></script>
<script type="text/javascript" src="angular-chartjs-doughnut-directive.js"></script>

The latest version of chartjs can be found on its official website: http://www.chartjs.org

Add a dependency to the module in your own module.

var myModule = angular.module('MyModule', ['angular.directives-chartjs-doughnut']);

Use the directive in your HTML files with the following code:

<div ang:chartjs:doughnut data-chartjs-model="scopeVariableName"></div>

Parameters

  • data-chartjs-model (string: required) The name of the attribute in the $scope to use as input of the doughnut chart. The attribute in question should have the following structure:

    {value: 40, color: '#949FB1'},
    {value: 120, color: '#4D5360'}
];
