Getting started with Angular Smith Chart component

24 May 2022 / 14 minutes to read

This section explains you the steps required to create a Smith Chart and demonstrate the basic usage of the Smith Chart control.

Setup Angular Environment

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

Copied to clipboard
npm install -g @angular/cli

Create an Angular Application

Start a new Angular application using below Angular CLI command.

Copied to clipboard
ng new my-app
cd my-app

Adding Syncfusion TreeMap package

All the available Essential JS 2 packages are published in npmjs.com registry.

To install treemap component, use the following command.

Copied to clipboard
npm install @syncfusion/ej2-angular-charts --save

The —save will instruct NPM to include the treemap package inside of the dependencies section of the package.json.

Registering TreeMap Module

Import TreeMap module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-charts [src/app/app.module.ts].

Copied to clipboard
import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the SmithchartModule for the Smithchart component
import { SmithchartModule } from '@syncfusion/ej2-angular-charts';
import { AppComponent }  from './app.component';

@NgModule({
  //declaration of ej2-angular-smithchart module into NgModule
  imports:      [ BrowserModule, SmithchartModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }
  • Modify the template in app.component.ts file to render the ej2-angular-charts component [src/app/app.component.ts].
Copied to clipboard
import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  selector: 'app-container',
  // specifies the template string for the Smithchart component
  template: `<ejs-smithchart style='display: block;' id='container'></ejs-smithchart>`,
  encapsulation: ViewEncapsulation.None
})
export class AppComponent  { }

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

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

The below example shows a basic Smithchart.

Module Injection

Smithchart component are segregated into individual feature-wise modules. In order to use a particular feature, you need to inject its feature service in the AppModule. In the current application, we are going to modify the above basic smithchart to visualize transmission lines. For this application we are going to use tooltip and legend feature of the smithchart. Please find relevant feature service name and description as follows.

  • SmithchartLegendService - Inject this provider to use legend feature.
  • TooltipRenderService - Inject this provider to use tooltip feature.

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

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { SmithchartComponent } from '@syncfusion/ej2-angular-charts';
import { SmithchartLegendService, TooltipRenderService } from '@syncfusion/ej2-angular-charts';

@NgModule({
   imports: [
       BrowserModule,
   ],
   declarations: [AppComponent, SmithchartComponent],
   bootstrap: [AppComponent],
   providers: [ SmithchartLegendService, TooltipRenderService ]
})

Add Series to Smithchart

Smithchart had two type of specification for adding series.

  • dataSource - Using this, Data object can bind directly by specifying the resistance and reactance values, series add to smithchart.
  • points - Using this, collection of resistance and reactance values can bind directly to render series.

Below sample demonstrate adding two series to smithchart both ways.

  • First series Transmission1 shows dataSource bound series.
  • Second series Transmission2 shows points bound series.
