Question

我已经在这几个小时了，似乎无法让我的分组条形图表现出来。特别是试图获得每个栏周围'g'翻译属性的适当宽度。

我尝试了多种方法，这似乎是最优雅的，虽然我对其他解决方案开放。目标是这样的：http://www.cagrimmett.com/til/2016/04/26/responsive-d3-bar-chart.html

这是一个解决方案。这是所需的输出吗？尝试调整窗口大小。

JS FIDDLE

调整功能：

function resize() {
console.log('----resize function----');
// update width
width = parseInt(d3.select('#chart-area').style('width'), 10);
width = width - margin.left - margin.right;

height = parseInt(d3.select("#chart-area").style("height"));
height = height - margin.top - margin.bottom;
console.log('----resiz width----'+width);
console.log('----resiz height----'+height);
// resize the chart

    x0.rangeRoundBands([0, width], .5);
x1.domain(rateNames).rangeRoundBands([0, x0.rangeBand()]);
y.range([height, 0]);

yAxis.ticks(Math.max(height/50, 2));
xAxis.ticks(Math.max(width/50, 2));

d3.select(svg.node().parentNode)
  .style('width', (width + margin.left + margin.right) + 'px');

svg.selectAll('.g')
  .attr("transform",function(d) { 
    return "translate(" + x0(d.category) + ",0)"; 
    });
    svg.selectAll('.g').selectAll("rect").attr("width", x1.rangeBand())
    .attr("x", function(d) { return x1(d.rate); })
svg.selectAll(".legend rect")
  .attr("x", width - 18);
svg.selectAll('.legend text')
    .attr("x", width - 24)  
svg.select('.x.axis').call(xAxis.orient('bottom')); 
}

我对resize函数做了一些更改。这就是原因：

x0和x1范围（两者）必须在调整大小时重置：

x0.rangeRoundBands([0,width],.5);
x1.domain(rateNames).rangeRoundBands([0,x0.rangeBand()]);
y.range([height, 0]);

在调整大小功能中强制设置了（10,0）的翻译，并且您无法将宽度应用于（组）。基本上，您只需要调用原始渲染中包含宽度和高度变化的所有代码。看看调整大小功能。
重新渲染底部的X轴包含x刻度的静态值：

svg.select('.x.axis').call(xAxis.orient('bottom')).selectAll("text").attr("x",55);

刚删除了attr("x", 55)

希望这会有所帮助。：）
