This section explains you the steps required to create a simple range navigator and demonstrate the basic usage of the range navigator control.

Dependencies

The list of minimum dependencies required to use an range navigator are follows:

|-- @syncfusion/ej2-react-charts
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-pdf-export
    |-- @syncfusion/ej2-file-utils
    |-- @syncfusion/ej2-compression
    |-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-calendars
    |-- @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.

    npm install -g create-react-app

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

   create-react-app quickstart --template typescript
   cd quickstart
   npm start

To set-up a React application in JavaScript environment, run the following command.
```
  create-react-app quickstart
  cd quickstart
  npm start
```

Install Syncfusion packages using below command.

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

Add Range Navigator to the Project

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

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

function App()  {

    return  (<RangeNavigatorComponent></RangeNavigatorComponent>);

};
export default App;

Now run the npm start command in the console, it will run your application and open the browser window.

   npm start

The below example shows a basic Range Navigator.

index.jsx
index.tsx
import { RangeNavigatorComponent } from '@syncfusion/ej2-react-charts';
import * as React from "react";
import * as ReactDOM from "react-dom";
class App extends React.Component {
    render() {
        return <RangeNavigatorComponent id="charts"/>;
    }
};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import { RangeNavigatorComponent} from '@syncfusion/ej2-react-charts';
import * as React from "react";
import * as ReactDOM from "react-dom";

class  App  extends  React.Component  {

  render() {
    return <RangeNavigatorComponent id="charts" />
  }

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

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 AppModule. In the current application, we are going to modify the above basic chart to visualize sales data for a particular year. For this application we are going to use line series, tooltip, data label, category axis and legend feature of the chart. Please find the relevant feature service name and description as follows.

AreaSeries - Inject this module in to services to use area series.
DateTime - Inject this module in to services to use date time feature.
RangeTooltip - Inject this module in to services to use tooltip feature.

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

import { AreaSeries, DateTime, Inject, RangeNavigatorComponent, RangeTooltip} from '@syncfusion/ej2-react-charts';
import * as React from "react";
import * as ReactDOM from "react-dom";

function App()  {

    return <RangeNavigatorComponent id='charts'>
      <Inject services={[AreaSeries, DateTime, RangeTooltip]} />
    </RangeNavigatorComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

Populate Range Navigator with Data

Now, we are going to provide data to the range navigator. Add a series object to the range navigator by using series property. Now map the field names x and y in the JSON data to the xName and yName properties of the series, then set the JSON data to dataSource property.
Since the JSON contains Datetime data, set the valueType range Navigator to Category. By default, the axis valueType is Numeric.

index.jsx
index.tsx
import { AreaSeries, DateTime, Inject, RangeNavigatorComponent, RangenavigatorSeriesCollectionDirective, RangenavigatorSeriesDirective, RangeTooltip } from '@syncfusion/ej2-react-charts';
import * as React from "react";
import * as ReactDOM from "react-dom";
import { bitCoinData } from 'default-data.ts';
function App() {
  const data = bitCoinData;

  return <RangeNavigatorComponent id='charts' valueType='DateTime' labelFormat='MMM-yy' value={[new Date('2017-09-01'), new Date('2018-02-01')]}>
    <Inject services={[AreaSeries, DateTime, RangeTooltip]} />
    <RangenavigatorSeriesCollectionDirective>
      <RangenavigatorSeriesDirective dataSource={data} xName='x' yName='y' type='Area' width={2} />
    </RangenavigatorSeriesCollectionDirective>
  </RangeNavigatorComponent>;
};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import {
  AreaSeries, DateTime, Inject, RangeNavigatorComponent, RangenavigatorSeriesCollectionDirective,
  RangenavigatorSeriesDirective, RangeTooltip
} from '@syncfusion/ej2-react-charts';
import * as React from "react";
import * as ReactDOM from "react-dom";
import { bitCoinData } from 'default-data.ts';

function App() {

  const data: object[] = bitCoinData;

  return <RangeNavigatorComponent id='charts'
    valueType='DateTime' labelFormat='MMM-yy' value={[new Date('2017-09-01'), new Date('2018-02-01')]}>
    <Inject services={[AreaSeries, DateTime, RangeTooltip]} />
    <RangenavigatorSeriesCollectionDirective>
      <RangenavigatorSeriesDirective dataSource={data} xName='x' yName='y' type='Area' width={2} />
    </RangenavigatorSeriesCollectionDirective>
  </RangeNavigatorComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

The tooltip is useful to show the selected data. You can enable the tooltip by setting the enable property as true in tooltip object and by injecting RangeTooltip module into the services.

index.jsx
index.tsx
import { AreaSeries, DateTime, Inject, RangeNavigatorComponent, RangenavigatorSeriesCollectionDirective, RangenavigatorSeriesDirective, RangeTooltip } from '@syncfusion/ej2-react-charts';
import * as React from "react";
import * as ReactDOM from "react-dom";
import { bitCoinData } from 'default-data.ts';
function App() {
  const data = bitCoinData;
  const tooltip = { enable: true, displayMode: 'Always' };
  return <RangeNavigatorComponent id='charts' valueType='DateTime' labelFormat='MMM-yy' value={[new Date('2017-09-01'), new Date('2018-02-01')]} tooltip={tooltip}>
    <Inject services={[AreaSeries, DateTime, RangeTooltip]} />
    <RangenavigatorSeriesCollectionDirective>
      <RangenavigatorSeriesDirective dataSource={data} xName='x' yName='y' type='Area' width={2} />
    </RangenavigatorSeriesCollectionDirective>
  </RangeNavigatorComponent>;
};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import {
  AreaSeries, DateTime, Inject, RangeNavigatorComponent, RangenavigatorSeriesCollectionDirective,
  RangenavigatorSeriesDirective, RangeTooltip, RangeTooltipSettingsModel
} from '@syncfusion/ej2-react-charts';
import * as React from "react";
import * as ReactDOM from "react-dom";
import { bitCoinData } from 'default-data.ts';

function App() {

  const data: object[] = bitCoinData;
  const tooltip: RangeTooltipSettingsModel = { enable: true, displayMode: 'Always' };

  return <RangeNavigatorComponent id='charts'
    valueType='DateTime' labelFormat='MMM-yy' value={[new Date('2017-09-01'), new Date('2018-02-01')]}
    tooltip={tooltip}>
    <Inject services={[AreaSeries, DateTime, RangeTooltip]} />
    <RangenavigatorSeriesCollectionDirective>
      <RangenavigatorSeriesDirective dataSource={data} xName='x' yName='y' type='Area' width={2} />
    </RangenavigatorSeriesCollectionDirective>
  </RangeNavigatorComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
