Getting started with Angular Stock chart component

11 Jul 202420 minutes to read

This section explains you the steps required to create a simple StockChart and demonstrate the basic usage of the StockChart component in an Angular environment.

To get start quickly with Angular Stock Charts using CLI and Schematics, you can check on this video:

Setup Angular Environment

You can use Angular CLI to setup your Angular applications.
To install Angular CLI use the following command.

npm install -g @angular/cli

Create an Angular Application

Start a new Angular application using below Angular CLI command.

ng new my-app
cd my-app

Installing Syncfusion StockChart package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

  1. Ivy library distribution package format
  2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-charts package to the application.

npm install @syncfusion/ej2-angular-charts --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-charts@ngcc package to the application.

npm install @syncfusion/ej2-angular-charts@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

@syncfusion/ej2-angular-charts:"20.2.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Add StockChart component

Modify the template in app.component.ts file to render the ej2-angular-charts component [src/app/app.component.ts].

import { ChartAllModule, StockChartAllModule } from '@syncfusion/ej2-angular-charts'
import { Component,ViewEncapsulation } from '@angular/core';

@Component({
imports: [
  ChartAllModule, StockChartAllModule
],
standalone: true,
selector: 'app-root',
// specifies the template string for the Charts component
template: `<ejs-stockchart id='chart-container'></ejs-stockchart>`,
encapsulation: ViewEncapsulation.None
})
export class AppComponent { }

Now use the app-container in the index.html instead of default one.

<app-container></app-container>
  • Now run the application in the browser using the below command.
npm start

Module Injection

Chart component are segregated into individual feature-wise modules. In order to use a particular feature, you need to inject its feature service in the app.component.ts. In the current application, we are going to modify the above basic chart to visualize sales stock value of a company.
For this application we are going to use candle series, tooltip, data label, datetime axis and legend feature of the chart. Please find relevant feature service name and description as follows.

  • CandleSeriesService - Inject this provider to use candle series.
  • LegendService - Inject this provider to use legend feature.
  • TooltipService - Inject this provider to use tooltip feature.
  • DataLabelService - Inject this provider to use datalabel feature.
  • DateTimeService - Inject this provider to use datetime feature.

These modules should be injected to the provider section as follows,

    import { Component } from '@angular/core';
    import { ChartAllModule, StockChartAllModule } from '@syncfusion/ej2-angular-charts'
    import { DateTimeService, LegendService, TooltipService } from '@syncfusion/ej2-angular-charts';
    import { DataLabelService, CandleSeriesService} from '@syncfusion/ej2-angular-charts';

    @Component({
        imports: [
            ChartAllModule, 
            StockChartAllModule
        ],
        standalone: true,
        providers: [ DateTimeService, LegendService, TooltipService, DataLabelService, CandleSeriesService ]
    })

Populate Chart with Data

This section explains how to plot below JSON data to the chart.

    export class AppComponent implements OnInit {
    public chartData: Object[];
    ngOnInit(): void {
        // Data for chart series
        this.chartData = [{
            "x": new Date('2012-04-02T00:00:00.000Z'),
            "open": 320.705719,
            "high": 324.074066,
            "low": 317.737732,
            "close": 323.783783,
            "volume": 45638000
        }, {
            "x": new Date('2012-04-03T00:00:00.000Z'),
            "open": 323.028015,
            "high": 324.299286,
            "low": 319.639648,
            "close": 321.631622,
            "volume": 40857000
        }, {
            "x": new Date('2012-04-04T00:00:00.000Z'),
            "open": 319.544556,
            "high": 319.819824,
            "low": 315.865875,
            "close": 317.892883,
            "volume": 32519000
        }, {
            "x": new Date('2012-04-05T00:00:00.000Z'),
            "open": 316.436432,
            "high": 318.533539,
            "low": 314.599609,
            "close": 316.476471,
            "volume": 46327000
        }]

    }

}

Add a series object to the chart by using series property and then set the JSON data to dataSource property.

Since the JSON contains datetime data, set the valueTypefor horizontal axis to DateTime. By default, the axis valueType is Numeric.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartAllModule, StockChartAllModule } from '@syncfusion/ej2-angular-charts'
import { CategoryService, LineSeriesService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
imports: [
         ChartAllModule, StockChartAllModule
    ],

providers: [ CategoryService, LineSeriesService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-stockchart id="chart-container" >
        <e-stockchart-series-collection>
            <e-stockchart-series [dataSource]='stockchartData' type='Candle' xName='date' High='high' Low='low' Open='open' Close ='close' Name='Apple'></e-stockchart-series>
        </e-stockchart-series-collection>
    </ejs-stockchart>`
})
export class AppComponent implements OnInit {
    public stockchartData?: Object[];
    ngOnInit(): void {
        // Title for stock chart
        this.stockchartData = chartData;
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Add Stock Chart Title

You can add a title using title property to the chart to provide quick information to the user about the data plotted in the chart.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartAllModule, StockChartAllModule } from '@syncfusion/ej2-angular-charts'
import { CategoryService, LegendService, TooltipService, DataLabelService, LineSeriesService} from '@syncfusion/ej2-angular-charts'




import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
imports: [
         ChartAllModule, StockChartAllModule
    ],

providers: [ CategoryService, LegendService, TooltipService, DataLabelService, LineSeriesService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-stockchart id="chart-container"
    [title]='title'>
        <e-stockchart-series-collection>
            <e-stockchart-series [dataSource]='stockchartData' type='Candle' xName='date' High='high' Low='low' Open='open' Close ='close' Name='Apple'></e-stockchart-series>
        </e-stockchart-series-collection>
    </ejs-stockchart>`
})
export class AppComponent implements OnInit {
    public stockchartData?: Object[];
    public title?: string;
    ngOnInit(): void {
        // Title for chart
        this.title = 'AAPL Stock Price';
        this.stockchartData = chartData;
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Add Stock Chart Crosshair

Crosshair has a vertical and horizontal line to view the value of the axis at mouse or touch position.

Crosshair lines can be enabled by using enable property in the crosshair. Likewise tooltip label for an axis can be enabled by using enable property of crosshairTooltip in the corresponding axis.

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




import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
imports: [
         ChartModule, StockChartAllModule, ChartAllModule
    ],

providers: [ CategoryService, LegendService, CandleSeriesService ],
standalone: true,
    selector: 'app-container',
    template: `<ejs-stockchart id="chart-container"
    [title]='title' [crosshair]='crosshair'>
        <e-stockchart-series-collection>
            <e-stockchart-series [dataSource]='stockchartData' type='Candle' xName='date' High='high' Low='low' Open='open' Close ='close' Name='Apple'></e-stockchart-series>
        </e-stockchart-series-collection>
    </ejs-stockchart>`
})
export class AppComponent implements OnInit {
    public stockchartData?: Object[];
    public title?: string;
    crosshair?: Object;
    ngOnInit(): void {
        // Title for chart
        this.title = 'AAPL Historical';
        this.crosshair = { enable: true };
        this.stockchartData = chartData;
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Trackball

Trackball is used to track a data point closest to the mouse or touch position. Trackball marker indicates the closest point and trackball tooltip displays the information about the point. To use trackball feature, we need to inject CrosshairService and TooltipService into the NgModule.providers.

Trackball can be enabled by setting the enable property of the crosshair to true and shared property in tooltip to true in chart.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule, ChartAllModule, StockChartAllModule } from '@syncfusion/ej2-angular-charts'
import { DateTimeService, LineSeriesService } from '@syncfusion/ej2-angular-charts'
import { LegendService, DataLabelService, TooltipService, CrosshairService } from '@syncfusion/ej2-angular-charts'




import { Component, OnInit } from '@angular/core';

@Component({
imports: [
         ChartModule, StockChartAllModule, ChartAllModule
    ],

providers: [ DateTimeService, LineSeriesService, LegendService, DataLabelService,
                 TooltipService, CrosshairService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-stockchart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title' [crosshair]='crosshair' [tooltip]='tooltip'>
        <e-stockchart-series-collection>
            <e-stockchart-series [dataSource]='chartData' type='Line' xName='x' yName='y' name='John' width=2 [marker]='marker'></e-stockchart-series>
