这里是实际结果:

我需要这个结果:

我怎样才能在没有填充的情况下显示最后一行? 真的是thx的家伙。

当你想要
成为线条时,在SVG中使用
stroke
属性而不是
fill
。您应该通过attr回调函数中的
索引
来控制特定数据

 svg.selectAll('.line')
   .data(data)
   .enter()
   .append("path")
   .attr("class", "line")
   .attr("clip-path", "url(#clip)")
   .attr('fill', function(d, i) {
     return i < 4 ? colors[i % colors.length] : 'none';
   })
   .attr('stroke', function (d, i) {
     return i >= 4 ? colors[i % colors.length] : 'none';
   })
   .attr("d", line);
svg.selectAll(“.line”)
.数据(数据)
.输入()
.append(“路径”)
.attr(“类”、“行”)
.attr(“剪辑路径”、“url(#剪辑)”)
.attr('fill',函数(d,i){
返回i<4种颜色[i%colors.length]:“无”;
})
.attr('stroke',函数(d,i){
返回i>=4种颜色[i%colors.length]:“无”;
})
.attr(“d”,行);

我解决了这个问题,但无论如何,我认为你的解决方案比我的好:D
