看起来angular-chart.js不支持Chart.js的第2版。下面是一个片段，显示了一个工作图表。它包括chart.js的v1.1.1

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">

  </div>
</body>

</html>

Answer 2

您的数据绑定错误

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

您的控制器中没有可变图表数据或图表标签。你以不同的方式命名它们。

实际上，属性的顺序相反。应该是chart-data =“data”chart-labels =“labels”

来自http://jtblin.github.io/angular-chart.js/

的示例

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

Answer 3

在html data =＆＃34; chart-data＆＃34;将是chart-data =＆＃34;数据＆＃34;

Answer 4

尝试使用代码时出现此错误：

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

似乎有一个版本不匹配，尝试与我自己的项目相同的错误。请参阅Chart.js的V1.1.1，正如@dustin已经回答的那样。

选中fiddle。

Angular-Chart.js它不显示图表
