Question

我需要帮助解决有关如何在xAxis和yAxis的每个值上绘制通道的问题。

现在我有了这个结果：

我需要这样的结果：

我认为它类似于：

svg.append("g")
    .attr("class", "y axis")
    .call(yAxis);

但我不确定...... 如果有人有想法......告诉我。

真的感谢所有回复

您可以为刻度线添加第二组轴功能，为网格添加另一组轴功能。 https://jsfiddle.net/ermineia/ah2bv6t5/

var xGrid = d3.svg.axis()
    .scale(x)
    .ticks(24)
    .tickSize(-height)
    .tickPadding(10)    
    .tickSubdivide(true)    
    .orient("bottom")
    .tickFormat('');
var xAxis = d3.svg.axis()
    .scale(x)
    .ticks(24)
    .tickSize(5)
    .tickPadding(10)    
    .tickSubdivide(true)    
    .orient("bottom");

var yGrid = d3.svg.axis()
    .scale(y)
    .ticks(5)
    .tickPadding(10)
    .tickSize(-width)
    .tickSubdivide(true)    
    .orient("left")
    .tickFormat('');
var yAxis = d3.svg.axis()
    .scale(y)
    .ticks(5)
    .tickPadding(10)
    .tickSize(5)
    .tickSubdivide(true)    
    .orient("left");

svg.append("g")
    .attr("class", "x axis")
    .attr("transform", "translate(0," + height + ")")   
    .call(xGrid);

svg.append("g")
    .attr("class", "x axis")
    .attr("transform", "translate(0," + height + ")")   
    .call(xAxis);

svg.append("g")
    .attr("class", "y axis")
    .call(yGrid);

svg.append("g")
    .attr("class", "y axis")
    .call(yAxis);

为所有xAxis和yAxis添加行
