1import { useEffect } from "react"
2import { Chart } from "chart.js";
3function Example() {
4 useEffect(() => {
5 var ctx = document.getElementById('myChart').getContext('2d');
6 var myChart = new Chart(ctx, {
7 type: 'line',
8 data: {
9 labels: ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"],
10 datasets: [{
11 data: [86, 114, 106, 106, 107, 111, 133],
