Use Different Value on Mouseover in angular nvd3

Question

I have a data set that contains a frequency per hundred and an absolute count. The data set looks like this:

$scope.data = [
    {
        key: "Cumulative Return",
        values: [
                {
                    "label" : "A" ,
                    "value" : 15  ,
                    "data"  : 486
                } ,
                {
                    "label" : "B" ,
                    "value" : 11  ,
                    "data"  : 403
                } ,
                {
                    "label" : "C" ,
                    "value" : 10  ,
                    "data"  : 374
                } ,
                {
                    "label" : "D" ,
                    "value" : 9  ,
                    "data"  : 362
                } ,
                {
                    "label" : "E" ,
                    "value" : 8  ,
                    "data"  : 321
                } ,
                {
                    "label" : "F" ,
                    "value" : 6  ,
                    "data"  : 246
                } ,
                {
                    "label" : "G" ,
                    "value" : 4  ,
                    "data"  : 187
                } ,
                {
                    "label" : "H" ,
                    "value" : 1  ,
                    "data"  : 42
                }
            ]
        }
    ]

Included in this plunker, you can see that when mousing over each bar, it reads A 15.0 etc. I would like to be able to have a different value displayed, specifically "count", as the mouseover behavior, but do not see any such option in the documentation. I'd like it to read A 486, B 403, etc.

How can I accomplish this?

Use tooltip contentGenerator config

tooltip: {
   contentGenerator: function(record) {        
      return '<p><span style="background-color:'+record.color+';display: inline-block; height:12px; width:12px;vertical-align: middle;"></span>&nbsp;' + record.data.label + ' ' + record.data.data + '</p>';
   }
},

var app = angular.module('plunker', ['nvd3']);

app.controller('MainCtrl', function($scope) {
  $scope.options = {
    chart: {
      type: 'discreteBarChart',
      height: 450,
      margin: {
        top: 20,
        right: 20,
        bottom: 50,
        left: 55
      },
      x: function(d) {
        return d.label;
      },
      y: function(d) {
        return d.value + (1e-10);
      },
      showValues: true,
      valueFormat: function(d) {
        return d3.format(',.4f')(d);
      },
      tooltip: {
        contentGenerator: function(record) {        
          return '<p><span style="background-color:'+record.color+';display: inline-block; height:12px; width:12px;vertical-align: middle;"></span>&nbsp;' + record.data.label + ' ' + record.data.data + '</p>';
        }
      },
      duration: 500,
      xAxis: {
        axisLabel: 'X Axis'
      },
      yAxis: {
        axisLabel: 'Y Axis',
        axisLabelDistance: -10
      }
    }
  };

  $scope.data = [{
    key: "Cumulative Return",
    values: [{
        "label": "A",
        "value": 15,
        "data": 486
      },
      {
        "label": "B",
        "value": 11,
        "data": 403
      },
      {
        "label": "C",
        "value": 10,
        "data": 374
      },
      {
        "label": "D",
        "value": 9,
        "data": 362
      },
      {
        "label": "E",
        "value": 8,
        "data": 321
      },
      {
        "label": "F",
        "value": 6,
        "data": 246
      },
      {
        "label": "G",
        "value": 4,
        "data": 187
      },
      {
        "label": "H",
        "value": 1,
        "data": 42
      }
    ]
  }]
});

This is very close to what I want. Is there a way to keep the color box as well? — black_sheep07, May 04 '17 at 13:14
