带圆角的甜甜圈图-可以吗? [英] Doughnut chart with rounded corners - is it possible?

问题描述

我需要将其实现为甜甜圈图-我四处寻找css/svg/canvas解决方案，但找不到任何可靠的方法.

I need to implement this as doughnut chart - I looked around for css/svg/canvas solutions but couldn't find any reliable way of doing it.

我知道每个段都可以有完整的圆角，但这不是我想要的.

I know I could have fully rounded corners of each segment, but that's not what I'm looking for.

推荐答案

我会使用此答案与这一个

.palette {
  --g:20px; /* The gap between shapes*/
  --s:50px; /* the size*/

  height: 300px;
  width: 300px;
  position:relative;
  display:inline-block;
  overflow:hidden;
  filter: url('#goo');
}
.palette > * {
  position:absolute;
  top:0;
  left:0;
  right:0;
  bottom:0;
  border:var(--s) solid var(--c,red);
  border-radius:50%;
  clip-path:polygon(
    calc(50% + var(--g)/2) 50%, 
    calc(50% + var(--g)/2) 0%, 
    100% 0%,
    100% calc(33.745% - var(--g)/2),
    50% calc(50% - var(--g)/2)); 
}
.color1 {
  transform:rotate(72deg);
  --c:blue;
}
.color2 {
  transform:rotate(144deg);
  --c:orange;
}
.color3 {
  transform:rotate(-72deg);
  --c:green;
}
.color4 {
  transform:rotate(-144deg);
  --c:purple;
}

<div class="palette">
  <div class="color1"></div>
  <div class="color2"></div>
  <div class="color3"></div>
  <div class="color4"></div>
  <div class="color5"></div>
</div>


<svg style="visibility: hidden; position: absolute;" width="0" height="0" xmlns="http://www.w3.org/2000/svg" version="1.1">
  <defs>
        <filter id="goo"><feGaussianBlur in="SourceGraphic" stdDeviation="5" result="blur" />    
            <feColorMatrix in="blur" mode="matrix" values="1 0 0 0 0  0 1 0 0 0  0 0 1 0 0  0 0 0 19 -9" result="goo" />
            <feComposite in="SourceGraphic" in2="goo" operator="atop"/>
        </filter>
    </defs>
