Dynamic Data Loading for React Charts
Show how to fetch and update data in TanStack React Charts dynamically using async functions and React hooks like `useState` and `useEffect` for real-time data visualization.
import React, { useState, useEffect } from 'react';
import { Chart } from 'react-charts';
Imports necessary hooks from React and the Chart component from react-charts library.
function MyChart() {
const [data, setData] = useState([]);
useEffect(() => {
const fetchData = async () => {
const response = await fetch('https://api.example.com/data');
const result = await response.json();
setData(result);
};
fetchData();
}, []);
const axes = React.useMemo(
() => [
{ primary: true, type: 'linear', position: 'bottom' },
{ type: 'linear', position: 'left' }
],
[]
);
Defines a component MyChart with a state for data. Uses useEffect to fetch data asynchronously on component mount and updates the data state. useMemo is used to setup chart axes.
return (
<div>
<Chart data={data} axes={axes} />
</div>
);
}
Renders the Chart component using the fetched data and defined axes.
export default MyChart;
Exports the MyChart component for use in other parts of the application.
