Question

我在尝试整合从api获得的数据时遇到错误。

我在index.html中包含了以下文件：

<script src="http://cdnjs.cloudflare.com/ajax/libs/d3/3.3.9/d3.min.js" charset="utf-8"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/nvd3/1.8.1/nv.d3.min.js"></script>
<script src="http://cmaurer.github.io/angularjs-nvd3-directives/lib/angularjs-nvd3-directives/dist/angularjs-nvd3-directives.js"></script>

这是我的HTML代码：

<div class="col-md-4 overflow-graph">
   <nvd3-line-chart
     data="exampleData"
     id="exampleId"
     xAxisTickFormat="xAxisTickFormatFunction()"
     yAxisTickFormat="yAxisTickFormatFunction()"
     width="550"
     height="350"
     showXAxis="true"
     showYAxis="true">
     <svg></svg>
   </nvd3-line-chart>
</div>

这是我从

获取数据的地方

$scope.exampleData = function(){
   for(var count in $scope.skuproduceCart) {
     var forecast = $scope.skuproduceCart[count].forecast;
   }
   return forecast;
};

预测返回具有结构

的对象数组

[Object, Object, Object]

这是我得到的错误：
