我拥有的CSS同心圆图像 我需要在给定 json 列表的情况下动态显示项目,但我需要知道的是如何将所有项目放在正确的位置。我想做一些类似的事情 A 层(内圆)= 距中心 20 像素,B 层(距中心第二个圆)= 距中心 120 像素,依此类推 并用(距离中心,角度)对来定位项目,从顶部开始的角度为 0。 有没有办法做到这一点?或者用更简单的方法来做?
import React from 'react'
import styles from './test.module.css'
export default function RadarComponent() {
return (
<div className={styles.container}>

<div className={styles.circleOne}>
<div className={styles.circleTwo}>
<div className={styles.circleThree}>
<div className={styles.circleFour}>
</div>
</div>
</div>
</div>
</div>
);
}
.container{
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
border: 1px solid #000;
}
.circleOne{
border-radius: 50% 50% 50% 50% / 50% 50% 50% 50% ;

我尝试使用 ChartJs 雷达,但问题是我无法使各部分具有不同的颜色,并且数据集中添加的一项会更改所有项目的整体位置,因为雷达图具有相对位置。

我建议一种相当简单的方法 - 将每个斑点作为背景放置在一个细长元素中,该元素的高度为圆的半径,并根据其子位置(0 到 6)旋转该元素。
此代码片段还通过将标签放置在每个旋转元素内的元素中来将标签放置到位 - 并再次旋转回来以使它们全部水平。
注意:此代码片段还将背景圆圈绘制为 CSS 背景,但如果您确实需要它们成为 4 个单独的元素,请使用您的原始代码。
