现场演示:
首先,您应该删除所有的幻数,以保持代码的干净性和可移植性
例如,这个:
pathStart += 125;
如何正确地画圆弧是一个数学问题。代码如下:
path.attr("d", function (d, i) {
const sx = 0;
const sy = height/2;
const a=width/2;
const b = ((data1.length-1)/2-i)*distanceBetween;
const c = Math.sqrt(a * a + b * b);
const angle=Math.atan(a/b);
let r;
if(b===0){
r=0;
}else{
r=1/2*c/Math.cos(angle);//also equals c/b*(c/2)
// r=c/b*(c/2);
}
return `M${sx},${sy} A${r},${r} 0 0,${b>0?1:0} ${width},${height/2}`;
});

-最新用户图表开发如何绘制路径?我是否只需创建一个svg路径并尝试推送两个cx、cy点以形成直线?-我该如何让它弯曲呢?如果你能解释的话,这可能会解决合并数据位的问题——如果你能解释的话——甚至更棒@老郡睡觉时间,明天见。我已经添加了合并功能——但是如果少于4组,路径就会中断——因此它可能无法处理动态数据——这个版本试图对数学进行评论——这里有一个常数1.5来计算b——这是导致错误的原因吗
