海图角的js加载数据 [英] Angular Js Loading data for Chart

问题描述

我想创建图表（使用chart.js之库）采用NG-重复。

I am trying to create charts( Using Chart.js Lib ) using ng-repeat.

编辑： PLUNKER

HTML

<div class="graph-display" ng-controller="jsonServerBox">
<div class="bar-chart-box" ng-repeat="module in ocw.modules"> 
  <canvas class="chart chart-bar" data="{{module.data}}" labels="{{module.labels}}" series="{{module.series}}"></canvas>
</div>
</div>

JS：

app.controller('jsonServerBox', function($scope, $http) {
  var json = {"modules":[
                {
                   "series":"SeriesA",
                   "data":["90", "99", "80", "91", "76", "75", "60", "67", "59", "55"],
                   "labels":["01", "02", "03", "04", "05", "06", "07","08","09","10"]
                },

                {
                   "series":"SeriesB",
                   "data":["90", "99", "80", "91", "76", "75", "60", "67", "59", "55"],
                   "labels":["01", "02", "03", "04", "05", "06", "07","08","09","10"]
                }

        ]}; 
    $scope.ocw = json;
    });

和我收到以下错误：

Syntax Error: Token 'module.data' is unexpected, expecting [:] at column 3 of the expression [{{module.data}}] starting at [module.data}}].

请帮忙。

推荐答案

分配直接从View范围变量，如数据=module.data标签=module.labels系列=module.series 。

Assign scope variables directly from View like data="module.data" labels="module.labels" series="module.series".

同时提供数据和放大器不要使用interpolution指令;标贴到指令。由于 chart.js之的实现是基于隔离的范围

Don't use interpolution directive while providing data & lables to directive. Because the chart.js implementation is based on isolated scope

HTML

<div class="graph-display" ng-controller="jsonServerBox">
<div class="bar-chart-box" ng-repeat="module in ocw.modules"> 
  <canvas class="chart chart-bar" data="module.data" labels="module.labels" series="{{module.series}}"></canvas>
</div>
</div>

这可以帮助你。谢谢你。

This could help you. Thanks.

更新1：

其实你都错过了几件事。

Actually you were missed couple of thing.

"series": ["SeriesA"],
"data": [["90", "99", "80", "91", "76", "75", "60", "67", "59", "55"]],

在code的变化是

Changes in your code are

1. 裹系列内部阵列改变系列：SeriesA，到系列：SeriesA]


2. 里面裹阵列数据阵列，因为它需要维数组作为输入。
