ChartJS

Basic Usage

To Use, make sure to include the following .js files above your app:

<scriptsrc="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.10/angular.min.js"></script><scriptsrc="//cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.1-beta.2/Chart.min.js"></script><scriptsrc="angles.js"></script>

Next, make sure to add "angles" to your Angular app requirements:

varapp=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:

<canvascharttype="Line" options="options" data="chart" width="500" height="300"></canvas>

Charts can also be added with shorter, aliased types

<canvasbarchartoptions="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

<canvasbarchartresponsive=trueoptions="options" data="chart"></canvas>

the legend attribute auto generate a legend after canvas container

<canvasbarchartlegend=trueoptions="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.
