Scatter Chart in Angular Charts

3 Feb 202624 minutes to read

Scatter

To render a scatter 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 Scatter in your chart configuration. This indicates that the data should be displayed as individual points scattered across the chart.

  2. Inject the ScatterSeries module: Use the @NgModule.providers method to inject the ScatterSeriesService module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering the scatter series are available in your chart.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { ScatterSeriesService, LegendService} from '@syncfusion/ej2-angular-charts'
import { Component, OnInit } from '@angular/core';

@Component({
imports: [
         ChartModule
    ],

providers: [ ScatterSeriesService, LegendService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='series1' type='Scatter' xName='x' yName='y' name='Male' opacity=0.7 [marker]='marker'></e-series>
            <e-series [dataSource]='series2' type='Scatter' xName='x' yName='y' name='Female' opacity=0.7 [marker]='marker'></e-series>
        </e-series-collection>

        let value1: number = 70;
        let i: number;
        for (i = 1; i < 120; i++) {
            if (Math.random() > 0.5) {
                value += Math.random();
            } else {
                value -= Math.random();
            }
            value = value < 60 ? 60 : value > 90 ? 90 : value;

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 { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { ScatterSeriesService, LegendService} from '@syncfusion/ej2-angular-charts'
import { Component, OnInit } from '@angular/core';

@Component({
imports: [
         ChartModule
    ],

providers: [ ScatterSeriesService, LegendService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='series1' type='Scatter' xName='x' yName='y' name='Male' opacity=0.7 [marker]='marker'></e-series>
            <e-series [dataSource]='series2' type='Scatter' xName='x' yName='y' name='Female' opacity=0.7 [marker]='marker'></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    public series1?: Object;

        let point1: Object;
        let value: number = 80;
        let value1: number = 70;
        let i: number;
        for (i = 1; i < 120; i++) {
            if (Math.random() > 0.5) {
                value += Math.random();
            } else {
                value -= Math.random();
            }
            value = value < 60 ? 60 : value > 90 ? 90 : value;

            } else {
                value1 -= Math.random();
            }

Series customization

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

Fill

Use the fill property to set the fill color for empty points.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { ScatterSeriesService, LegendService} from '@syncfusion/ej2-angular-charts'

        let series2: Object[] = [];
        let point1: Object;
        let value: number = 80;

            if (Math.random() > 0.5) {
                value += Math.random();
            } else {
                value -= Math.random();
            }
            value = value < 60 ? 60 : value > 90 ? 90 : value;
            point1 = { x: 120 + (i / 2), y: value.toFixed(1) };
            series1.push(point1);
        }
        for (i = 1; i < 120; i++) {
            if (Math.random() > 0.5) {

bootstrapApplication(AppComponent).catch((err) => console.error(err));

Opacity

The opacity property controls the transparency of the fill and affects how the series blends with background or overlapping series.

import { NgModule } from '@angular/core'

Empty points

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

Mode

Use the mode property to control handling of empty points. Available modes: Gap, Drop, Zero, Average. The default mode is Gap.

Fill

Use the fill property to customize the fill color of empty points in the series.

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { ISeriesRenderEventArgs } from '@syncfusion/ej2-charts'
import { ScatterSeriesService, LegendService} from '@syncfusion/ej2-angular-charts'
import { Component, OnInit } from '@angular/core';
import { scatterData } from './datasource';

@Component({
imports: [
         ChartModule
    ],

providers: [ ScatterSeriesService, LegendService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" (seriesRender)='seriesRender($event)' [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Scatter' xName='x' yName='y' name='Male'></e-series>
        </e-series-collection>

            edgeLabelPlacement: 'Shift',
            labelFormat: '{value}cm'
        };
        this.primaryYAxis = {

Point render

The pointRender event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.

        this.marker = {  width: 10, height: 10 };
        this.chartData = scatterData;
    }
    public pointRender(args: IPointRenderEventArgs)  {
