這里的問(wèn)題是您正在交換y和height邏輯，它應(yīng)該是：
.attr("y", d => yScale(d.percent))
.attr("height", d => height - margin.bottom - margin.top - yScale(d.percent))
或者，如果您將工作高度設(shè)置為...
height = totalHeight - margin.bottom - margin.top
...它可以只是：
.attr("y", d => yScale(d.percent))
.attr("height", d => height - yScale(d.percent))
最重要的是（這解決了您的第二個(gè)問(wèn)題），您錯(cuò)誤地使用了 Bostock 的保證金約定。您應(yīng)該g根據(jù)邊距翻譯該組，然后將所有小節(jié)附加到該已翻譯組中，而無(wú)需再次翻譯它們。此外，將軸的組附加到該g組。
話雖如此，這是具有這些更改的代碼：

你需要減去 100 的百分比
