Getting error "data.map is not a function" using angular-nvd3

Question

I'm getting some deep nvd3 error when I try to configure a simple line chart using angular-nvd3.

I edited the example plunker given and it seems it might be my data that is malformatted, since swapping the options only still works.

Here is an malfunctioning plunkr: http://plnkr.co/edit/fznNKBw6hwNYavfZ3Nvi?p=preview

the options:

  $scope.options = {
    "chart": {
      "type": "lineChart",
      "height": 450,
      "useInteractiveGuideline": true,
      "dispatch": {},
      "xAxis": {
        "axisLabel": "Months"
      },
      "yAxis": {
        "axisLabel": "Team size",
      }
    }
  };

the data:

$scope.data = {
    "key": "Monthly",
    "values": [{
      "x": 0,
      "y": 2
    }, {
      "x": 1,
      "y": 6
    }, {
      "x": 2,
      "y": 10
    }]
  }

Anybody who can spot the issue?

I replaced your scope.data with a sample one from the nvd3 site:

      $scope.data = sinAndCos();

    /*Random Data Generator */
    function sinAndCos() {
        var sin = [],sin2 = [],
            cos = [];

        //Data is represented as an array of {x,y} pairs.
        for (var i = 0; i < 100; i++) {
            sin.push({x: i, y: Math.sin(i/10)});
            sin2.push({x: i, y: i % 10 == 5 ? null : Math.sin(i/10) *0.25 + 0.5});
            cos.push({x: i, y: .5 * Math.cos(i/10+ 2) + Math.random() / 10});
        }

        //Line chart data should be sent as an array of series objects.
        return [
            {
                values: sin,      //values - represents the array of {x,y} data points
                key: 'Sine Wave', //key  - the name of the series.
                color: '#ff7f0e'  //color - optional: choose your own line color.
            },
            {
                values: cos,
                key: 'Cosine Wave',
                color: '#2ca02c'
            },
            {
                values: sin2,
                key: 'Another sine wave',
                color: '#7777ff',
                area: true      //area - set to true if you want this line to turn into a filled area chart.
            }
        ];
    };

And that works in this plunkr:

So this means something is wrong with the data component of what you are trying to do. Experiment by adding/subtracting from your data element and see if that helps.

Edit: Your data object was badly formed: it should be in this format:

  $scope.data = [{
        "key" : "Monthly",
        values : [{
                "x" : 1,
                "y" : 6,
                "color" : 'blue'
            }, {
                "x" : 2,
                "y" : 10,
                "color" : 'red'
            }
        ]
    }
  ];  

So from the docs the data object expects an array and then the values are a further array of value objects:
