Chart.JS 在 JSFiddle 上使用 Angular.JS

Question

I'm trying to create a tested graph mimicking this chart from this documentation .

In my JSFiddle ( https://jsfiddle.net/bheng/2pcmubwq/ )

I tried adding all the links needed in the resources:

• https://code.angularjs.org/1.4.8/angular.js
• https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.js
• https://cdnjs.cloudflare.com/ajax/libs/angular-chart.js/0.10.2/angular-chart.js

HTML

<canvas id="bar" class="chart chart-bar"
  chart-data="data" chart-labels="labels"> chart-series="series"
</canvas>

JS

angular.module("app", ["chart.js"]).controller("BarCtrl", function ($scope) {
  $scope.labels = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];
  $scope.series = ['Series A', 'Series B'];

  $scope.data = [
    [65, 59, 80, 81, 56, 55, 40],
    [28, 48, 40, 19, 86, 27, 90]
  ];
});

Result

I see no errors in the console, but this white screen.

What did I do wrong to make my graph didn't render?

Every angularJs app have to be mounted in the document using those directives: ng-app ng-controller
Your fiddle fixed: https://jsfiddle.net/nmwypgdq/9/

<div ng-app="app" ng-controller="BarCtrl">
  <canvas id="bar" class="chart chart-bar" chart-data="data" chart-labels="labels" chart-series="series"></canvas>
</div>

$scope object passed by controller callback is available in your template. You can reference its properties and methods in the template. Thus chart-data="data" binds HTML element property chart-data with $scope.data defined in the controller callback. chart-labels is bound with $scope.labels and so on...
