我有如下带有刻度线的分组条形图。

由于某些条形不是从 0 位置开始，因此它看起来不像一个组。我想将那些 y 轴刻度线向上移动 half of the distance between current tick position and the next tick position ，因此分组条出现在 2 条黑线内。我认为在那种情况下它会更好看，也许我们可以应用一些 css 来区分每个相邻的组。

我不知道该怎么做，所以我四处搜索并没有找到类似的东西。有可能实现吗？

任何帮助是极大的赞赏 :)

最佳答案

这些线对应于轴的刻度，它们由轴生成器自动创建和定位。

无需过多的重构或定制，您可以在它们创建后简单地将它们向下移动:

d3.selectAll(".y.axis .tick line").each(function(){
    d3.select(this)
        .attr("transform", "translate(0," + yScale.bandwidth()/2 + ")")
});

这是具有该更改的代码:

$(document).ready(function() {
  render_chart();
});

function render_chart() {
