d3响应条形图

我一直在这个小时，似乎无法让我的分组条形图表现。特别是试图为每个栏周围的'g'翻译属性获取适当的宽度。d3响应条形图

我已经尝试了多种方法，这似乎是最优雅的，虽然我打开其他解决方案。我们的目标是这样的：http://www.cagrimmett.com/til/2016/04/26/responsive-d3-bar-chart.html

这里有一个解决方案。这是期望的输出吗？尝试调整窗口的大小。

JS FIDDLE

大小功能：

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')); 
}

我做出了调整大小功能的一些变化。这里的原因：

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

翻译的（10,0）正在力大小调整功能设置和：

X0和X1的范围（两者）都对调整大小重置您无法将宽度应用于（组）。基本上，你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。
重新绘制X轴在底部包括对x的静态值蜱：

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

只是删除了attr("x", 55)

希望这有助于。 :)
