我是d3.js的新手。如何在水平刻度上显示酒吧 - 在D3.js
我创建了一个条形图&通过将tickSize附加到Y轴，在图表区域添加了水平线。但是线条正在通过酒吧。
var yAxis = d3.svg.axis()
.scale(y)
.orient("left")
.ticks(10)
.tickSize(-width);
请检查附件的截图。 黑色水平线应位于酒吧下方。
请帮忙。

var margin = { top: 20, right: 20, bottom: 100, left: 40 },
width = this.props.chartWidth - margin.left - margin.right,
height = this.props.chartHeight - margin.top - margin.bottom;
var x = d3.scale.ordinal().rangeRoundBands([0, width], .05);
var y = d3.scale.linear().range([height, 0]);
//Remove the svg object if created previously for Clear purpose
$("#" + this.props.chartContainerId).show();
//d3.select("svg").remove();
var chart = d3.select("#" + this.props.chartContainerId)
.append("svg") //append svg element inside #chart
.attr("width", width + (2 * margin.left) + margin.right) //set width
.attr("height", height + margin.top + margin.bottom + 100) //set height
.style("padding-top", "5px");
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
