React Apexcharts CandleStick Chart Example Tutorial
In this tutorial, we will step-by-step describe how to create candlestick chart in React js functional component using the Apexcharts, and Bootstrap libraries.
A candlestick chart is a well-known chart in the investment domain.
It helps investors or financial experts predict the price movement of stock, currency, or commodities over a particular time.
A candlestick chart comprises green and red rectangular vertical thin lines. Candlestick has long wicks, also known as shadows.
It represents high and low prices for a particular season.
The length of the wicks and the size of the body can provide an understanding of the volatility and strength of the price movement during the designated period.
We will show you how to use and integrate Apexchart’s candlestick chart module in React js app.
How to Implement CandleStick Chart in React with React Apexcharts
- Step 1: Build React Project
- Step 2: Install Apexcharts Package
- Step 3: Create Function Component
- Step 4: Build CandleStick Chart Component
- Step 5: Update App Js Entry
- Step 6: Run App in Browser
Build React Project
Here is a simple and straight process to define a brand up a new React project:
The first thing you have to do is to install Node and npm; you can grab it from here.
Open the command-prompt, enter the given command and execute the command to install the React framework.
npx create-react-app my-react-appNext, get inside the project folder.
cd my-react-appInstall Apexcharts Package
Further, we need to install the dependencies such as React apexcharts, and bootstrap libraries.
npm i react-apexcharts apexcharts bootstrap --legacy-peer-depsCreate Function Component
Create components/ folder with the ApexCandleStick.js file.
Here is a basic code to define the functional component in React.
import React from 'react'
function ApexCandleStick() {
return (
<div></div>
)
}
export default ApexCandleStickBuild CandleStick Chart Component
We need a sample data, chart library to be added at the top to build the candlestick chart in React.
Add the given code inside the components/ApexCandleStick.js file.
import React from "react";
import Chart from "react-apexcharts";

export default ApexCandleStick;Update Main Entry
You need to search the App.js file, inside the src/ folder.
You need to import the ApexCandleStick component to make the ApexCandleStick component globally available in your React project.
import React from "react";
import "bootstrap/dist/css/bootstrap.min.css";
import ApexCandleStick from "./components/ApexCandleStick";
function App() {
return (
<div className="container mt-3">
<h2 className="mb-3">React Apexcharts CandleStick Chart Example</h2>
<ApexCandleStick />
</div>
);
}
export default App;Run App in Browser
Run the following command to start the application server.
npm starthttp://localhost:3000Wait for couple of seconds, your app will be served on above url and look something like this:
Conclusion
Candlestick charts are widely popular amidst financial and technical analysts, they use candlestick charts to recognise trends, patterns, and potential price movements in the financial market.
In this tutorial, we have learned how to build a simple candlestick chart in React js. To draw the candlestick chart we used the Apexchart’s chart API.
We hope this tutorial will help you.
