Bubble Chart in React Chart

Bubble

To render a bubble series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  1. Set the series type: Define the series type as Bubble in your chart configuration. This indicates that the data should be displayed as a bubble series in the chart.

  2. Inject the BubbleSeries module: Inject BubbleSeries module into the services. This step is essential, as it ensures that the necessary functionalities for rendering the bubble series are available in your chart.

import * as React from "react";
import * as ReactDOM from "react-dom/client";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, BubbleSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    const primaryxAxis = { title: 'Literacy Rate', minimum: 60, maximum: 100, interval: 5 };
    const primaryyAxis = { title: 'GDP growth rate', minimum: -2, maximum: 16, interval: 2 };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='GDP vs Literacy Rate'>
            <Inject services={[BubbleSeries]}/>
            <SeriesCollectionDirective>
                <SeriesDirective dataSource={data} xName='x' yName='y' size='size' type='Bubble' name='pound'>
                </SeriesDirective>

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

import * as React from "react";
import * as ReactDOM from "react-dom/client";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, BubbleSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';
function App() {
    const primaryxAxis = { title: 'Literacy Rate', minimum: 60, maximum: 100, interval: 5 };
    const primaryyAxis = { title: 'GDP growth rate', minimum: -2, maximum: 16, interval: 2 };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='GDP vs Literacy Rate'>
            <Inject services={[BubbleSeries]}/>
            <SeriesCollectionDirective>
                <SeriesDirective dataSource={data} xName='x' yName='y' size='size' type='Bubble' name='pound'>
                </SeriesDirective>
            </SeriesCollectionDirective>
          </ChartComponent>;

Series customization

The following properties can be used to customize the bubble series.

Fill

The fill property determines the color applied to the series.

import * as React from "react";
import * as ReactDOM from "react-dom/client";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, BubbleSeries } from '@syncfusion/ej2-react-charts';

    const primaryxAxis = { title: 'Literacy Rate', minimum: 60, maximum: 100, interval: 5 };
    const primaryyAxis = { title: 'GDP growth rate', minimum: -2, maximum: 16, interval: 2 };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='GDP vs Literacy Rate'>

    { x: 61.3,  y: 14.5, size: 0.162,  text: 'Nigeria' }
];

Opacity

The opacity property controls the transparency of the fill and affects how the series blends with background or overlapping series. For example, opacity={0.5} makes each bubble semi-transparent.

import * as React from "react";
import * as ReactDOM from "react-dom/client";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, BubbleSeries } from '@syncfusion/ej2-react-charts';
import { data } from './datasource';

    const primaryxAxis = { title: 'Literacy Rate', minimum: 60, maximum: 100, interval: 5 };
    const primaryyAxis = { title: 'GDP growth rate', minimum: -2, maximum: 16, interval: 2 };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='GDP vs Literacy Rate'>
            <Inject services={[BubbleSeries]}/>
            <SeriesCollectionDirective>
                <SeriesDirective dataSource={data} xName='x' yName='y' size='size' type='Bubble' name='pound' opacity={0.5}>

    { x: 61.3,  y: 14.5, size: 0.162,  text: 'Nigeria' }
];

Size mapping

Use the size property to map the size of each bubble to a numeric field in the data source. For example, size='size' maps a numeric field from the data source to the bubble size, allowing relative comparison between data points.

Empty points

Data points with null or undefined values are considered empty. Empty data points are not plotted on the chart.

Mode

Use the mode property of emptyPointSettings to control how empty points are rendered. Available modes are Gap (leave a break, the default), Drop (Ignores the empty point during rendering), Zero (plot as zero), and Average (plot as the average of neighboring points).
