HighCharts - Bubble Charts

Hello, this article is about how we can create a Bubble chart using Highcharts in js. Chart showing basic use of bubble series with a custom tooltip formatter. Bubble charts are great for comparing three dimensions of data without relying on color or 3D charts.

CDN for using Bubble chart

<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/highcharts-more.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<script src="https://code.highcharts.com/modules/export-data.js"></script>
<script src="https://code.highcharts.com/modules/accessibility.js"></script>

Create a HTML file i.e, Bubble Chart.html and use below code.

<figure class="highcharts-figure">
    <div id="container"></div>
    <p class="highcharts-Brahmadescription">
        Created By Brahma Prakash Shukla
    </p>
</figure>

Now, create a CSS file for styling the Bubble chart.

.highcharts-figure,
.highcharts-data-table table {
    min-width: 310px;
    max-width: 800px;
    margin: 1em auto;
}

#container {
    height: 400px;
}

.highcharts-tooltip h3 {
    margin: 0.3em 0;
}

.highcharts-data-table table {
    font-family: Verdana, sans-serif;
    border-collapse: collapse;
    border: 1px solid #ebebeb;
    margin: 10px auto;
    text-align: center;
    width: 100%;
    max-width: 500px;
}

.highcharts-data-table caption {
    padding: 1em 0;
    font-size: 1.2em;
    color: #555;
}

.highcharts-data-table th {
    font-weight: 600;
    padding: 0.5em;
}

.highcharts-data-table td,
.highcharts-data-table th,
.highcharts-data-table caption {
    padding: 0.5em;
}

.highcharts-data-table thead tr,
.highcharts-data-table tr:nth-child(even) {
    background: #f8f8f8;
}

.highcharts-data-table tr:hover {
    background: #f1f7ff;
}

After that, create a JS file for showing data in Bubble chart.

Highcharts.chart('container', {

    chart: {
        type: 'bubble',
        plotBorderWidth: 1,
        zoomType: 'xy'
    },

    legend: {
        enabled: false
    },

    title: {
        text: 'Created By Brahma Prakash Shukla'
    },

    subtitle: {
        text: 'Bubble Chart'
    },

    accessibility: {
        point: {
            valueDescriptionFormat: '{index}. {point.name}, fat: {point.x}g, sugar: {point.y}g, obesity: {point.z}%.'
        }
    },

    xAxis: {
        gridLineWidth: 1,
        title: {
            text: 'X'
        },
        labels: {
            format: '{value}'
        },
        plotLines: [{
            color: 'black',
            dashStyle: 'dot',
            width: 2,
            value: 65,
            label: {
                rotation: 0,
                y: 15,
                style: {
                    fontStyle: 'italic'
                },
                text: 'Y'
            },
            zIndex: 3
        }],
        accessibility: {
            rangeDescription: 'Range: 60 to 100'
        }
    },

    yAxis: {
        startOnTick: false,
        endOnTick: false,
        title: {
            text: 'X'
        },
        labels: {
            format: '{value} gr'
        },
        maxPadding: 0.2,
        plotLines: [{
            color: 'black',
            dashStyle: 'dot',
            width: 2,
            value: 50,
            label: {
                align: 'right',
                style: {
                    fontStyle: 'italic'
                },
                text: 'Z',
                x: -10
            },

        }],
        accessibility: {
            rangeDescription: 'Range: 0 to 160 grams.'
        }
    },

            '<tr><th>C:</th><td>{point.z}%</td></tr>',
        footerFormat: '</table>',
        followPointer: true
    },

    plotOptions: {
        series: {
            dataLabels: {
                enabled: true,
                format: '{point.name}'
            }
        }
    },

    series: [{

});

Now, your chart will look like this,
