【问题描述】：
我想在 React 中使用 Nivo 库构建一个简单的图表来表示 API 响应中数据的百分比值。
响应中的数据如下所示：https://run.mocky.io/v3/7c46c4ce-09c0-4f95-b4e1-84ae10bd24ab
我需要用一个非常简单的折线图来表示这些数据。
到目前为止，我的组件中有这段代码：
import React, {useState, useEffect} from 'react';
import axios from 'axios';
import {useParams} from 'react-router-dom';
import Loader from '../Components/Loader';
import { Bar } from "@nivo/bar";
function ArtistDetail() {
const {artist_uuid} = useParams()
const url = `https://run.mocky.io/v3/${artist_uuid}`;
const [artist, setArtist] = useState({
loading: false,
data: null,
error: false
})
let content = null;
useEffect(() => {
setArtist({
loading: true,
data: null,
error: false
})
axios.get(url)
.then(response => {
setArtist({
loading: false,
data: response.data,
error: false
})
})
.catch(() => {
setArtist({
loading: false,
data: null,
error: true
})
})
}, [url])
if(artist.error) {
content = <p>There was an error loading an artist.</p>
}
if(artist.loading) {
content = <p><Loader/></p>
}
if(artist.data) {
content =

return (

<button className="btn btn-scroll-down">Scroll down</button>
</div>
</section>
</main>
}
return (
<div>
{content}
</div>
)
}
export default ArtistDetail;
我不知道如何在这个 div 中显示百分比数据：
<div className="graph-line">
<span className="line" style={{ width: 47 + "%" }}>
47%
</span>
</div>;
看起来像这样
对于图表，我使用了来自here的代码
