Basic Highcharts Bubble Drilldown

Question

I'm new at Highcharts. I'm trying to create a Drilldown Bubble Chart.

I took the basic column drilldown as a starting point,

http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/drilldown/basic/

chart: {
  type: 'column'
},
title: {
  text: 'Basic drilldown'
},
xAxis: {
  type: 'category'
},

legend: {
  enabled: false
},

plotOptions: {
  series: {
    borderWidth: 0,
    dataLabels: {
      enabled: true
    }
  }
},

series: [{
  name: 'Things',
  colorByPoint: true,
  data: [{
    name: 'Animals',
    y: 5,
    drilldown: 'animals'
  }, {
    name: 'Fruits',
    y: 2,
    drilldown: 'fruits'
  }, {
    name: 'Cars',
    y: 4,
    drilldown: 'cars'
  }]
}],
drilldown: {
  series: [{
    id: 'animals',
    data: [
      ['Cats', 4],
      ['Dogs', 2],
      ['Cows', 1],
      ['Sheep', 2],
      ['Pigs', 1]
    ]
  }, {
    id: 'fruits',
    data: [
      ['Apples', 4],
      ['Oranges', 2]
    ]
  }, {
    id: 'cars',
    data: [
      ['Toyota', 4],
      ['Opel', 2],
      ['Volkswagen', 2]
    ]
  }]
}

and edited it a bit, to get this,

http://jsfiddle.net/Slate_Shannon/kdwa9x7v/1/

$(function() {

$('#container').highcharts({
chart: {
  type: 'bubble'
},
title: {
  text: 'Basic drilldown'
},
xAxis: {
  type: 'linear'
},

legend: {
  enabled: false
},

plotOptions: {
  series: {
    borderWidth: 0,
    dataLabels: {
      enabled: true
    }
  }
},

series: [{
  name: 'Things',
  colorByPoint: true,
  data: [{
    name: 'Animals',
    x: 4,
    y: 5,
    z: 10,
    drilldown: 'animals'
  }, {
    name: 'Fruits',
    x: 14,
    y: 20,
    z: 20,
    drilldown: 'fruits'
  }, {
    name: 'Cars',
    x: 8,
    y: 9,
    z: 7,
    drilldown: 'cars'
  }]
}],
drilldown: {
  series: [{
    id: 'animals',
    data: [
      ['Cats', x: 5, y: 9, z: 7],
      ['Dogs', x: 8, y: 8, z: 9],
      ['Cows', x: 1, y: 5, z: 2],
      ['Sheep', x: 4, y: 7, z: 2],
      ['Pigs', x: 4, y: 5, z: 7]
    ]
  }, {
    id: 'fruits',
    data: [
      ['Apples', x: 2, y: 9, z: 6],
      ['Oranges', x: 6, y: 5, z: 1]
    ]
  }, {
    id: 'cars',
    data: [
      ['Toyota', x: 2, y: 8, z: 7],
      ['Opel', x: 8, y: 2, z: 4],
      ['Volkswagen', x: 4, y: 4, z: 4]
    ]
  }]
}
});
});

All I did was

change the chart type to "bubble",
add the x and z data,
change the xaxis to "linear"

And it doesn't work.

Can you see the problem?

Thanks much!

Good day.

The formatting of your drilldown data is incorrect, as hinted to in console. Currently you have:

data: [
    ['Cats', x: 5, y: 9, z:7],
    ['Dogs', x: 8, y: 8, z:9],
    // ...
]

This is half way between an array declaration and a object declaration. I'd suggest switching to each item being an object, like this:

data: [
    { name: 'Cats', x: 5, y: 9, z:7 },
    { name: 'Dogs', x: 8, y: 8, z:9 },
    // ...
]

Secondly, you haven't included the required Highcharts-more module which includes the bubble chart type. You can do that like this:

<script src="https://code.highcharts.com/highcharts-more.js"></script>

See this updated JSFiddle for a basic example of how it can work.
