这是我的代码,但它不是我想要的。我希望颜色分布不对称。
<svg width="300" height="300">
<linearGradient id="linearColors" x1="0" y1="0" x2="1" y2="1">
<stop offset="5%" stop-color="#01E400"></stop>
<stop offset="25%" stop-color="#FEFF01"></stop>
<stop offset="40%" stop-color="#FF7E00"></stop>
<stop offset="60%" stop-color="#FB0300"></stop>
<stop offset="80%" stop-color="#9B004A"></stop>
<stop offset="100%" stop-color="#7D0022"></stop>
</linearGradient>
<circle r="120" cx="150" cy="150" class="external-circle" stroke-width="4" fill="none" stroke="url(#linearColors)"></circle>
</svg>
我需要这样的效果。
答案 0 :(得分:8)
在检查之前:circle-drawing-with-svgs-arc-path ....我的解决方案很简单:我将圆圈分成六个圆弧,每个圆弧都有自己的直线渐变
数学解释:
角度= 360/6 = 60
Math.sin(Math.PI * 60/180)* 120 == 103.9230
Math.cos(Math.PI * 60/180)* 120 == 60.0000
