How to correctly use labels for radial plot in D3?
问题
我是新手D3,尝试创建类似于https://observablehq.com/@d3/radial-area-chart的径向图,使用合成数据集。这是我达到的结果:
正如您可能注意到的,我尝试使用从0到24的标签来显示数据中的24小时变化。我的问题是小时标签与圆圈线重叠。1) 如何将小时标签放置在内圆的每个相应线的中心(每小时一条线)上?2) 如何避免使此图的读者混淆径向刻度的0(显示0到180的范围)和小时的0?
我的代码在这里:https://jsfiddle.net/9swb8p6c/,合成数据.csv文件在下面。

I am new to D3 and trying to create a radial plot similar to this https://observablehq.com/@d3/radial-area-chart using synthetic dataset.This is the result I have reached:
As you might notice, I am trying to use labels from 0 to 24 to show 24 hours changes in my data. My problem is that there are labels for hours are overlapping with circle lines. 1) How can I place hour labels in the center of each respective line (line for each hour) in the inner circle? 2) How can I avoid confusing the reader of this plot to not confuse the 0 of radial scale (the one shows range from 0 to 180) and 0 of the hour?
My code is in: https://jsfiddle.net/9swb8p6c/ and synthetic_data.csv file is below this.

更改x轴变量解决了我的问题。我使用了.data(d3.range(0, 24))
,而不是.data(x.ticks(24))
。
const xAxis = (g) => g
.attr("font-family", "sans-serif")
.attr("font-size", 10)
.call((g) => g.selectAll("g")
.data(d3.range(0, 24)) // 创建一个小时值的数组
.join("g")
.each((d, i) => d.id = `hour-${i}`)
.call((g) => g.append("path")
.attr("stroke", "#000")
.attr("stroke-opacity", 0.2)
.attr("d", (d) => `
M${d3.pointRadial(x(d * 60), innerRadius)}
L${d3.pointRadial(x(d * 60), outerRadius)}
`))
.call((g) => g.append("path")
.attr("id", (d) => `hour-${d}`)
.datum((d) => [d * 60, (d + 1) * 60])
.attr("fill", "none")
.attr("d", ([a, b]) => `
M${d3.pointRadial(x(a), innerRadius-10)}
A${innerRadius},${innerRadius} 0,0,1 ${d3.pointRadial(x(b), innerRadius)}
`))
.call((g) => g.append("text")
.append("textPath")
.attr("startOffset", 6)
.attr("href", (d) => `#hour-${d}`)
.text((d) => d.toString().padStart(2, "0"))
.attr("text-anchor", "middle")
.attr("alignment-baseline", "middle")
.attr("transform", (d) => {
const angle = x(d * 60);
const radius = innerRadius - 20; // 减小半径以将标签靠近中心
return `translate(${d3.pointRadial(x(d * 60), radius)})`;
})
)
);
