我正在尝试使用dimple.js构建堆积条形图,我需要通过angular指令执行此操作,所以我正在使用angular-dimple

这是我编写的运行示例示例的代码:







    <script type="text/javascript">
        var app = angular.module("dimpleTestApp", ['angular-dimple']);


        app.controller('myCtrl', ['$scope', 'dataService', function($scope, dataService) {
        dataService.getData().then(function(response) {
        $scope.graphData = response.data;
        console.log($scope.graphData);
            });
        }])
        .service('dataService', ['$http', function($http) {
          return {
            getData: function() {
              return $http.get('data.json');
            }
          };
        }]);
</script>
</head>
<body ng-app='dimpleTestApp'>
    <div ng-controller="myCtrl">
    <graph data="graphData" orientation="horizontal">
        <x-axis field="Month"></x-axis>
        <y-axis field="Sales"></y-axis>
        <stacked-bar field="storeId" value="2"></stacked-bar>
    </graph>

    </div>

</body>


但是运行此代码时出现此错误:

谁能告诉我此应用程序有什么问题以及如何使它运行。

最佳答案

我已经通过更深入地研究角度酒窝库解决了这一问题。

他们的文档指令使用xy元素创建时出错,而在示例中他们提到了x-axisy-axis,因此当我对其进行更正时,将其更改为有效。

这是修改后的代码:

<graph data="graphData" orientation="horizontal">
        <x field="Month"></x>
        <y field="Sales"></y>
        <stacked-bar field="storeId" ></stacked-bar>
    </graph>
