This section explains the steps required to create a heat map and demonstrates the basic usage of the HeatMap component.
You can explore some useful features in the HeatMap component using the following video.
Dependencies
For using heat map, the following minimum requirements are needed.
|-- @syncfusion/ej2-react-heatmap
|-- @syncfusion/ej2-heatmap
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-data
|-- @syncfusion/ej2-svg-base
|-- @syncfusion/ej2-react-baseInstallation and configuration
To get started with the React application, create-react-app can be used to setup the application. To install create-react-app, run the following command.
npm install -g create-react-app
To create basic React application, run the following command.
create-react-app quickstart
Now, the application is created in the quickstart folder. Run the following command to navigate to the quickstart folder, and install the required npm packages.
cd quickstart
In the quickstart application, the Syncfusion component is added in the JavaScript file.
Creating a React application with TypeScript
To create React application with TypeScript, use the following command.
create-react-app quickstart --template typescript
Now, the application is created in the quickstart folder. Run the following command to navigate to the quickstart folder, and install the required npm packages.
cd quickstart
Adding Syncfusion packages
All the available Essential JS 2 packages are published in npmjs.com public registry. To install Heatmap package, use the following command.
npm install @syncfusion/ej2-react-heatmap --save
Adding HeatMap to the project
Now, you can start adding HeatMap component in the application. For getting started, add the HeatMap component in src/App.tsx file using following code.
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { HeatMapComponent } from '@syncfusion/ej2-react-heatmap';
export function App() {
return ( <HeatMapComponent id='heatmap'></HeatMapComponent> );
}
export default App;Use the npm start command to run the application in the browser.
npm start
The below example shows a basic HeatMap.
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { HeatMapComponent } from '@syncfusion/ej2-react-heatmap';
export function App() {
return ( <HeatMapComponent ></HeatMapComponent> );
}
const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { HeatMapComponent } from '@syncfusion/ej2-react-heatmap';
export function App() {
return ( <HeatMapComponent ></HeatMapComponent> );
}
const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);Module injection
The heat map components are segregated into individual feature-wise modules. To use its feature, you need to inject its feature service in the AppModule. In the current application,the basic heat map is modified to visualize sales revenue data for week, and the tooltip and legend features of the heat map are used. Find the relevant feature modules and descriptions as follows.
- Legend - Provides the legend feature by injecting it.
- Tooltip - Provides the tooltip feature by injecting it.
Now, import the above-mentioned modules from the heat map package and inject them into services.
import * as React from "react";
import * as ReactDOM from "react-dom";
import { HeatMapComponent, Inject, Legend, Tooltip} from '@syncfusion/ej2-react-heatmap';
export function App() {
return(<HeatMapComponent id='heatmap'>
<Inject services={[Legend, Tooltip]}/>
</HeatMapComponent>
);
}
const root = ReactDOM.createRoot(document.getElementById('heatmap'));
root.render(<App />);Populate heat map with data
This section explains how to populate the following two-dimensional array data to the heat map.
