我正在关注 Chart.js 示例。但是，当我尝试渲染该示例时，出现以下错误：

未捕获的类型错误：无法读取未定义的属性“绘制”

这是我正在关注的示例。我已经相应地做了所有事情，但我不知道为什么会导致这个问题。 http://carlcraig.github.io/tc-angular-chartjs/doughnut/

下面是我对该示例的实现。我的模块

angular.module('main')
    .controller('AboutController', ['$scope', function ($scope) {
         $scope.data = [
      {
          value: 300,
          color: '#F7464A',
          highlight: '#FF5A5E',
          label: 'Red'
      },
      {
          value: 50,
          color: '#46BFBD',
          highlight: '#5AD3D1',
          label: 'Green'
      },
      {
          value: 100,
          color: '#FDB45C',
          highlight: '#FFC870',
          label: 'Yellow'
      }
    ];

    // Chart.js Options
    $scope.options = {

        // Sets the chart to be responsive
        responsive: true,

        //Boolean - Whether we should show a stroke on each segment
        segmentShowStroke: true,

        //String - The colour of each segment stroke
        segmentStrokeColor: '#fff',

        //Number - The width of each segment stroke
        segmentStrokeWidth: 2,

        //Number - The percentage of the chart that we cut out of the middle
        percentageInnerCutout: 50, // This is 0 for Pie charts

        //Number - Amount of animation steps
        animationSteps: 100,

        //String - Animation easing effect
        animationEasing: 'easeOutBounce',

        //Boolean - Whether we animate the rotation of the Doughnut
        animateRotate: true,

        //Boolean - Whether we animate scaling the Doughnut from the centre
        animateScale: false,

        //String - A legend template
        legendTemplate: '<ul class="tc-chart-js-legend"><% for (var i=0; i<segments.length; i++){%><li><span style="background-color:<%=segments[i].fillColor%>"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>'

    };
    }]);

这是我的html代码

<canvas tc-chartjs-doughnut chart-options="options" chart-data="data" auto-legend></canvas>

我应该补充一点，我能够渲染图表的图例。 传奇

draw是一个 Chart.js 方法——你确定你已经包含了所有的依赖吗？

<script type="text/javascript" src="js/Chart.js"></script>
<script type="text/javascript" src="js/angular.js"></script>
<script type="text/javascript" src="js/tc-angular-chartjs.js"></script>

您还需要将其列为您的 app/ 的要求angular.module：

angular.module( 'main', ['tc.chartjs']);

确保您拥有兼容的 Chart.js 版本。1.0.2 版适用于您使用 tc-angular v1.0.11 的示例

确保除了 angular、tc-angular 和 Chart.js 之外，您没有加载其他库（至少开始时）。

试图重现您的错误，我很快就遇到了完全相同的问题 - 但是在运行$ bower install tc-angular-chartjs并复制所有代码之后，这就是结果，它工作正常。它还包括所需的脚本和模块依赖项，如教程中所示并由 Tina 提到
