我要做的是创建一个简单的圆环图。我目前只使用CSS(3),但我不知道是否可以不使用javascript。
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;
}
我想将绿色和蓝色显示为百分比。因此,绿色不是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。
非常感谢您的帮助。

stroke-dasharray
用于定义&#39;模式&#39;虚线使用(MDN)。通过提供单个值,您可以创建一个440px的短划线和440px的空间。 (440px大致是圆的圆周)。
stroke-dashoffset
有效地移动了破折号模式的起点(MDN)。
dash-offset
为220(stroke-dasharray
的一半)会产生半圆。 110 =四分之一圈等。

.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;
}
}

由于动画使用from
代替to
来制作动画,因此不支持动画的浏览器会显示完整的圆环图,而不是完全没有。这也可以使用内联CSS更改圆环图的彩色部分,同样的单个CSS动画可以用于任意数量的圆环图。
对svg
内容的解释:
stroke-dasharray
:在这种情况下,基本上是圆的总周长。
stroke-dashoffset
:着色的圆圈部分。零(0)表示所有着色的(100%),440(或任何你设置的圆周),没有任何着色(0%) )
circle
元素的属性:
r
:圆的半径
cx
:&#34;中心X&#34;。圆心(svg
元素左下角的X坐标)
cy
:&#34;中心Y&#34;。圆心(svg
元素左下角的Y坐标)
stroke-width
:将绘制甜甜圈的笔画宽度
stroke
:甜甜圈的颜色
