    |-- @syncfusion/ej2-charts
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-svg-base

Installation and configuration

You can use create-react-app to setup the applications. To install create-react-app run the following command.

Add Smith Chart to the Project

Now, you can start adding Smith Chart component in the application. For getting started, add the Smith Chart component in src/App.tsx file using following code.

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

class App extends React.Component {

Module Injection

Smithchart component are segregated into individual feature-wise modules. In order to use a particular feature, you need to inject its feature module using <Inject services={} /> method. 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 module name and description as follows.

  • SmithchartLegend - Inject this provider to use legend feature.
  • TooltipRender - Inject this provider to use tooltip feature.

Now import the above mentioned modules from smithchart package and inject it into the Smithchart component using <Inject services={} /> method.

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

class App extends React.Component {
render() {
  return ( <SmithchartComponent>
  <Inject services={[SmithchartLegend, TooltipRender]} />
  </SmithchartComponent> );
 }
}
export default App;

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.
