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

It looks like angular-chart.js doesn't support version 2 of Chart.js. Below is a snippet, that shows a working chart. It includes v1.1.1 of chart.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]
  ];
});

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

</html>

回答2:

Your data binding is wrong

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

You have no variable chart-data nor chart-labels in your controller. You named them differently.

In fact, the attributes are in reverse order. Should be chart-data="data" chart-labels="labels"

Example from http://jtblin.github.io/angular-chart.js/

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

回答3:

In html data="chart-data" would be chart-data="data"

回答4:

I was getting this error while trying your code:

(intermediate value)[e] is not a function angular chart

It seems there is a version mismatch, tried the same with my own project got the same error. Please take V1.1.1 of Chart.js, as already answered by @dustin.

Check this fiddle.
