我正在尝试显示水平条形图的条形标签，但它们没有显示在条形图的边缘，而是显示在条形图的顶部。我认为我的代码的“//水平条标签”部分有问题。代码如下，我还包含了我制作的图表的图片以及我希望它看起来像的图表:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Housing Tenure of DC Residents</title>
<style type="text/css">
.axis text{
font-family: Arial;
font-size: 13px;
color: #333333;
text-anchor: end;
}
.axis path {
fill:none;
stroke:#333333 ;
stroke-width: 1.5px;
shape-rendering: crispEdges
font-family: Arial;
}
.bar{
stroke: none;
fill: #037FAA;
}
.axis .label{
font-family: Arial;
font-size:13px;
color: #333333;
text-anchor: middle;
}
.textlabel{
font-family: Arial;
font-size:13px;

text-anchor: left;

Percentage,LabelD3
41.6,Own home
58.6,Rent home
最佳答案
而不是对水平条标签执行此操作
.attr("x", function(d){ return xScale(d["Percentage"]) + (xScale.range()/2); })
这样做
.attr("x", function(d){ return xScale(parseFloat(d["Percentage"])) ; })
.attr("y", function(d){ return yScale(d["LabelD3"]) + yScale.rangeBand()/2; })
