Angular-Chart.js 不显示图表

Question

我正在尝试使用 Angular-chart.js 它没有为我显示任何内容这是我的 javascript 和 html 页面

(function(){
 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]
    ];
 });
})();

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

</body>

</html>

我不明白错误在哪里，提前感谢您的帮助

Answer 1

您的数据绑定错误

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

您的控制器中没有变量图表数据或图表标签。你给它们取了不同的名字。

其实属性是倒序的。应该是 chart-data="data" chart-labels="labels"

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

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

Answer 2

在 html data="chart-data" 中将是 chart-data="data"

Answer 3

angular-chart.js 似乎不支持 Chart.js 的版本 2。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]
  ];
});

我在尝试您的代码时遇到此错误：

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

好像版本不匹配，用我自己的项目试了同样的错误。请使用 Chart.js 的 V1.1.1，正如@dustin 已经回答的那样。

检查此 fiddle。
