Angles.js
An angular.js wrapper for the Chart.js library.
New Update of ChartJS (Beta) allow more interaction with graph ( tooltips and png/jpg export of graphs)
Basic Usage
To Use, make sure to include the following .js files above your app:
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.10/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.1-beta.2/Chart.min.js"></script>
<script src="angles.js"></script>Next, make sure to add "angles" to your Angular app requirements:
var app = angular.module("anglesExample", ["angles"]);Charts are added using a canvas element with the following syntax, which corresponds to Chart.js. The data and options attributes refer to ng-models in the controller scope. You can name these whatever you want:
<canvas chart="Line" options="options" data="chart" width="500" height="300"></canvas>Charts can also be added with shorter, aliased types
<canvas barchart options="options" data="chart" width="500" height="300"></canvas>In your controller, make sure you provide the appropriate data and options per Chart.js documentation:
you can add responsive attribute to enable responsiveness of canvas
<canvas barchart responsive=true options="options" data="chart"></canvas>the legend attribute auto generate a legend after canvas container
<canvas barchart legend=true options="options" data="chart"></canvas>The template for this legend is a legendTemplate in the chart options
$scope.chart = {
labels : ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"],
datasets : [
{
fillColor : "rgba(151,187,205,0)",
strokeColor : "#e67e22",
pointColor : "rgba(151,187,205,0)",
pointStrokeColor : "#e67e22",
data : [4, 3, 5, 4, 6]
},
{
fillColor : "rgba(151,187,205,0)",
strokeColor : "#f1c40f",
pointColor : "rgba(151,187,205,0)",
pointStrokeColor : "#f1c40f",
data : [8, 3, 2, 5, 4]
}
],
};That's it. You can change the values of the chart just as you would with any other angular model.
