CSS3简单甜甜圈图



我想做的是创建一个简单的圆环图。我目前只使用CSS(3),但我不知道没有javascript是否可行。

到目前为止我所拥有的:http://jsfiddle.net/aBP5Q/

HTML:

<div class="donut-container" style="background: #9C0;">
    <div class="donut-inner">
        <div class="donut-label">HTML</div>
    </div>
</div>

CSS:

.donut-container {
    width: 150px;
    height: 150px;
    float: left;
    -webkit-border-radius: 75px;
    -moz-border-radius: 75px;
    border-radius: 75px;
    margin-right: 20px;
}
.donut-inner {
    width: 134px;
    height: 134px;
    position: relative;
    top: 8px;
    left: 8px;
    background: #FFF;
    -webkit-border-radius: 65px;
    -moz-border-radius: 65px;
    border-radius: 65px;
}
.donut-label {
    line-height: 130px;
    text-align: center;
    font-size: 20px;
}

我想展示绿色和蓝色作为主题。所以没有绿色是0%,全绿色(360度)是100%。如果可能的话,甚至可以在加载图表时使用简单的动画。

非常感谢你的帮助。

SVG获胜!

.item {
    position: relative;
    float: left;
}
.item h2 {
    text-align:center;
    position: absolute;
    line-height: 125px;
    width: 100%;
}
svg {
   -webkit-transform: rotate(-90deg);
    transform: rotate(-90deg);
}
.circle_animation {
  stroke-dasharray: 440; /* this value is the pixel circumference of the circle */
  stroke-dashoffset: 440;
}
.html .circle_animation {
    -webkit-animation: html 1s ease-out forwards;
    animation: html 1s ease-out forwards;
}

}
@keyframes css {

  }
}

它是如何工作的

stroke-dasharray用于定义虚线使用的"模式"(MDN)。通过提供一个值,您可以创建一个破折号为440px、空格为440px的图案。(440px大约是圆的周长)。

CCD_ 2有效地移动了虚线图案(MDN)的起始点。

220的dash-offsetstroke-dasharray的一半)将产生半圆。110=四分之一圆等

这个答案之所以可能,是因为Turnip的答案,但我做了一些重大更改,我将解释它是如何工作的:

.donutContainer {
    position: relative;
    float: left;
}
.donutContainer h2 {
    text-align:center;
    position: absolute;
    line-height: 125px;
    width: 100%;
}
svg {
    transform: rotate(-90deg);
}
.donut {
  stroke-dasharray: 440;
  -webkit-animation: donut 1s ease-out forwards;
  animation: donut 1s ease-out forwards;
}
@-webkit-keyframes donut {
  from {
    stroke-dashoffset: 440;
  }
}
@keyframes donut {
  from {
    stroke-dashoffset: 440;
  }
}
<div class="donutContainer">
    <h2>donut</h2>
    <svg width="160" height="160" xmlns="http://www.w3.org/2000/svg">
     <g>
      <title>Layer 1</title>
      <circle id="circle" style="stroke-dashoffset: 160;/* 160 of 440 */" class="donut" r="69.85699" cy="81" cx="81" stroke-width="8" stroke="#69aff4" fill="none"/>
     </g>
    </svg>
</div>
<div class="donutContainer">
    <h2>donut 2</h2>
    <svg width="160" height="160" xmlns="http://www.w3.org/2000/svg">
     <g>
      <title>Layer 1</title>
      <circle id="circle" style="stroke-dashoffset: 220;/* 220 of 440 */" class="donut" r="69.85699" cy="81" cx="81" stroke-width="8" stroke="#FEC007" fill="none"/>
     </g>
    </svg>
</div>

因为动画使用from而不是to来创建动画,所以不支持动画的浏览器将显示完整的圆环图,而不是完全不显示。这也使得只使用内联CSS就可以更改圆环图的彩色部分,并且相同的单个CSS动画可以适用于任何数量的圆环图。

svg物质的解释:

stroke-dasharray:在这种情况下,基本上是圆的总周长。

stroke-dashoffset:圆圈中着色的部分。零(0)表示所有着色在(100%)中,440(或您设置的周长)表示没有着色在(0%)中

circle元素的属性:

r:圆的半径

CCD_ 12:";中心X";。圆心(svg元素左下角的X坐标)

CCD_ 14:";中心Y";。圆心(svg元素左下角的Y坐标)

stroke-width:绘制圆环的笔划宽度

stroke:甜甜圈的颜色

我写了这篇评论回复,但太长了:

嗯。。。哦,这是第二圈的小提琴http://jsfiddle.net/LgtV2/。。。。它有三个馅饼部分。第一个圆(100%)有5个部分。你应该掌握它的工作原理,这样你就可以复制它了。我以前从来没有这样做过,我只是在看San发布的链接,但它看起来只是使用了多个Div和css3TRANSFORM来形成曲线,以及用于动画的伪选择器:before和:after。动画在加载页面时发生。。。例如:在加载div1之前,它有一个5的变换,它加载并有一个8的变换,:在加载之后,它有11的变换。
