Chart.js is treeshakable since chart.js V3 so you will need to import and register all elements you are using.
import {Chart, ArcElement} from 'chart.js'
Chart.register(ArcElement);
For all available imports and ways of registering the components you can read the normal chart.js documentation

I ran into the same issue earlier, found the solution on react-chartjs-2 documentation page: https://react-chartjs-2.netlify.app/docs/migration-to-v4#tree-shaking
import 'chart.js/auto';
import { Chart } from 'react-chartjs-2';
<Chart type='line' data={chartData} />
All you have to do is to add this line import 'chart.js/auto';

In my case this worked:
import React from "react";
import { ArcElement } from "chart.js";
import Chart from "chart.js/auto";
2π
import { Chart as ChartJS, ArcElement, Tooltip, Legend } from 'chart.js';
import { Pie } from 'react-chartjs-2';
ChartJS.register(ArcElement, Tooltip, Legend);
2π
You can simply use this. worked for me,
{import { Doughnut, Pie } from "react-chartjs-2";
import { Chart as ChartJS, ArcElement, Tooltip, Legend } from "chart.js";
ChartJS.register(ArcElement, Tooltip, Legend);}
and for changing the height and width values
{<Pie
data={data}
width={300}
height={300}
options={{ maintainAspectRatio: false }}
/>}

In react, I also faced the same issue with doughnut charts.npm i react-chartjs-2 chart.js
Documentation says to install this in frontend frameworks; I was using React.
import {Chart,ArcElement} from 'chart.js';
import {Doughnut} from 'react-chartjs-2'
Chart.register(ArcElement)
const data = {
};
function Graph() {
return (
<div></div>
)
}
export default Graph
after importing ArcElement from chart.js
and Chart.register(ArcElement)
fixed my issue
1π
In my case this is what worked for me : I imported chart & registrables & ArcElement in one import
import { Chart, registerables, ArcElement } from "chart.js";
Chart.register(...registerables);
Chart.register(ArcElement);
1π
from the react-chartjs-2 docs :
As you can see in migration to v4 guide:
v4 of this library, just like Chart.js v3, is tree-shakable. It means that you need to import and register the controllers, elements, scales, and plugins you want to use.
For a list of all the available items to import, see Chart.js docs.
So you should register missed components. For example, if you have Uncaught Error: "arc" is not a registered element. error, you should register ArcElement:
import { ArcElement } from "chart.js";
ChartJS.register(ArcElement);

[my app displayed on browser][1]

My app compiled without errors but my chart(Doghnut) is not been displayed on the browser.
here is my details component where i imported and used it
import React from 'react';
import { Card, CardHeader, CardContent, Typography } from '@material-ui/core';
import {Chart, ArcElement} from 'chart.js';
import { Doughnut } from 'react-chartjs-2';
import useStyles from './styles';
import useTransactions from '../../useTransactions';
Chart.register(ArcElement)
const Details = ({ title, subheader }) => {
const { total, chartData } = useTransactions(title);
const classes = useStyles();
return (
<Card className={title === 'Income' ? classes.income : classes.expense}>
<CardHeader title={title} subheader={subheader} />
<CardContent>
<Typography variant="h5">${total}</Typography>
<Doughnut data={chartData} />
</CardContent>
</Card>
);
};
export default Details;
here also is my package.json file

}
my app.js file where i imported my details component above
import React, { useEffect, useRef } from 'react';
import { Grid } from '@material-ui/core';
import { SpeechState, useSpeechContext } from "@speechly/react-client";
import { PushToTalkButton, PushToTalkButtonContainer } from '@speechly/react-ui';
import Details from './components/Details/Details';
import Main from './components/Main/Main';
import useStyles from './styles';
const App = () => {
const classes = useStyles();
const { speechState } = useSpeechContext();
const main = useRef(null);
const executeScroll = () => main.current.scrollIntoView() ;
useEffect(() => {
if (speechState === SpeechState.Recording) {
executeScroll();
}
}, [speechState]);
return (
<div>
<Grid className={classes.grid} container spacing={0} alignItems="center" justifyContent ="center" style={{ height: '100vh'}}>
<Grid item xs={12} sm={4} className={classes.mobile}>
<Details title="Income" />
</Grid>
<Grid ref={main} item xs={12} sm={3} className={classes.main}>
<Main />
</Grid>
<Grid item xs={12} sm={4} className={classes.desktop}>
<Details title="Income" />
</Grid>
<Grid item xs={12} sm={4} className={classes.last}>
<Details title="Expense" />
</Grid>
<PushToTalkButtonContainer>
<PushToTalkButton />
</PushToTalkButtonContainer>
</Grid>
</div>
);
};
export default App;
I do not know where the problem is coming from
here is my index.js file
import React from 'react';
import ReactDOM from 'react-dom';
import {SpeechProvider} from '@speechly/react-client';
import { Provider } from "./context/context";
import App from './App';
import './index.css';
ReactDOM.render(
<SpeechProvider appid='60b621bc-87ac-41e5-b500-0b7a66f96317' language='en-US'>
<Provider>
<App/>
</Provider>
</SpeechProvider>,
document.getElementById (βrootβ)
);
