angularjs - Angular Js Loading data for Chart

Question

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

EDIT : 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;
    });

And I'm getting following error:

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

Please help.

Answer 1

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

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>

This could help you. Thanks.

Update 1:

Actually you were missed couple of thing.

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

Changes in your code are

1. Wrap Series inside array changed "series": "SeriesA", to "series": ["SeriesA"]
2. Wrap data array inside array because it takes dimensional array as an input.

Check Working Plunkr for more info.

Thanks.
