Getting started with React Smith Chart component

4 Mar 202624 minutes to read

This section describes the steps to create a simple Smith Chart and demonstrates the basic usage of the Smith Chart component.

A quick video overview of the React Smith Charts setup is available:

Dependencies

Below is the list of minimum dependencies required to use the Smith Chart component.

  |-- @syncfusion/ej2-react-charts
      |-- @syncfusion/ej2-charts
      |-- @syncfusion/ej2-base
      |-- @syncfusion/ej2-data
      |-- @syncfusion/ej2-svg-base
      |-- @syncfusion/ej2-pdf-export
      |-- @syncfusion/ej2-compression
      |-- @syncfusion/ej2-file-utils
      |-- @syncfusion/ej2-react-base

Installation and configuration

To easily set up a React application, use the Vite CLI (npm create vite), which provides a faster development environment, smaller bundle sizes, and optimized builds compared to traditional tools like create-react-app. For detailed steps, refer to the Vite installation instructions. Vite sets up your environment using JavaScript and optimizes your application for production.

Note: To create a React application using create-react-app instead, refer to this documentation for more details.

To create a new React application, run the following command.

npm create vite@latest my-app

This command will prompt you for a few settings for the new project, such as selecting a framework and a variant.

Initial_setup

To set up a React application in TypeScript environment, run the following command.

npm create vite@latest my-app -- --template react-ts
cd my-app
npm run dev

To set up a React application in JavaScript environment, run the following command.

npm create vite@latest my-app -- --template react
cd my-app
npm run dev

Install Syncfusion® Smith Chart Package

All the available Essential® JS 2 packages are published in the npmjs.com public registry.
To install the Syncfusion® Smith Chart package, use the following command

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

The –save will instruct NPM to include the Smith Chart package inside of the dependencies section of the package.json.

Add Smith Chart to the project

Add the Smith Chart component to src/App.tsx using the following code.

import * as React from "react";
import { SmithchartComponent } from '@syncfusion/ej2-react-charts';

function App() {
  return ( <SmithchartComponent></SmithchartComponent> );
}
export default App;

Now run the npm run dev command in the console to start the development server. This command compiles your code and serves the application locally, opening it in the browser.

npm run dev

The below example shows a basic Smith Chart.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { SmithchartComponent } from '@syncfusion/ej2-react-charts';

function App() {
    return (<SmithchartComponent id="smithchart"></SmithchartComponent>);
}
export default App;
const root = ReactDOM.createRoot(document.getElementById('smithchart'));
root.render(<App />);
import * as React from "react";
import * as ReactDOM from "react-dom";
import { SmithchartComponent } from '@syncfusion/ej2-react-charts';

function App() {

  return ( <SmithchartComponent id="smithchart"></SmithchartComponent> );

}
export default App;
const root = ReactDOM.createRoot(document.getElementById('smithchart'));
root.render(<App />);

Module injection

Smith 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 AppModule. In the current application, we are going to modify the above basic Smith Chart to visualize transmission lines. For this application we are going to use tooltip, and legend feature of the Smith Chart. Please find relevant feature service name and description as follows.

  • SmithchartLegend - Inject this module in to services to use legend feature.
  • TooltipRender - Inject this module in to services to use tooltip feature.

Import the above-mentioned modules from the chart package and inject them into the services section of the Smith Chart component as follows.

import * as React from "react";
import { SmithchartComponent, SmithchartLegend, TooltipRender, Inject } from '@syncfusion/ej2-react-charts';

function App() {

  return ( <SmithchartComponent>
  <Inject services={[SmithchartLegend, TooltipRender]} />
  </SmithchartComponent> );

}
export default App;

Add series to Smith Chart

Smith Chart had two type of specification for adding series.

  • dataSource — Bind a data object directly by specifying resistance and reactance values; the series renders from the provided dataSource.
  • points — Provide a collection of resistance and reactance value points for the series.

Below sample demonstrate adding two series to Smith Chart both ways.

  • First series Transmission1 shows dataSource bound series.
  • Second series Transmission2 shows points bound series.
import * as React from "react";
import * as ReactDOM from "react-dom";
import { SmithchartComponent, SmithchartSeriesCollectionDirective, SmithchartSeriesDirective } from '@syncfusion/ej2-react-charts';
function App() {
    return (<SmithchartComponent id='smithchart'>
                        <SmithchartSeriesCollectionDirective>
                            <SmithchartSeriesDirective points={[

Enable marker to Smith Chart

You can add and customize the markers in the Smith Chart. This can be achieved by setting the visible property to true in the marker object. The sample below enables markers for the first series.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { SmithchartComponent, SmithchartSeriesCollectionDirective, SmithchartSeriesDirective } from '@syncfusion/ej2-react-charts';
function App() {
    return (<SmithchartComponent id='smithchart' title={{
            visible: true,
            text: 'Transmission lines applied for both impedance and admittance'
        }}>
                        <SmithchartSeriesCollectionDirective>
                            <SmithchartSeriesDirective points={[
            { resistance: 10, reactance: 25 }, { resistance: 8, reactance: 6 },
            { resistance: 6, reactance: 4.5 }, { resistance: 4.5, reactance: 2 },
            { resistance: 3.5, reactance: 1.6 }, { resistance: 2.5, reactance: 1.3 },

Enable dataLabel to Smith Chart marker

You can add data labels to improve the readability of the Smith Chart. This can be achieved by setting the visible property to true in the dataLabel object. Now, the data labels are arranged smartly based on series. The sample below enables data labels for the first series.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { SmithchartComponent, SmithchartSeriesCollectionDirective, SmithchartSeriesDirective } from '@syncfusion/ej2-react-charts';
function App() {
    return (<SmithchartComponent id='smithchart' title={{
            visible: true,
            text: 'Transmission lines applied for both impedance and admittance'
        }}>
                        <SmithchartSeriesCollectionDirective>
                            <SmithchartSeriesDirective points={[
