title: NVD3 force specific width of bar in bar chart
body: <p>I am trying to get a specific width value set on a nvd3 discrete bar chart. I can change the rect elements after the initial render, but it seems like there would be some way to designate a bar width in the set-up of the chart. </p>
  
  <p>Here is my current chart settings. </p>
  
  <pre><code>nv.addGraph -&gt;
    chart = nv.models.discreteBarChart()
      .x (d) -&gt;
        return d.label
      .y (d) -&gt;
        return d.value
      .staggerLabels(false).showValues(false)
      .color(['#56bd78']).tooltips(false)
      .margin({top: 0, right: 0, bottom: 30, left: 0})
  
    chart.tooltipContent (key, x, y, e, graph) -&gt;
      return '&lt;h3&gt;&lt;span&gt;' + parseFloat(y) + '&lt;/span&gt;&lt;em&gt;' +
               key + '&lt;/em&gt;&lt;/h3&gt;'
  
    chart.xAxis.tickFormat (d) -&gt;
        return d3.time.format('%b')(new Date('2013/'+d+'/01'))
    # chart.xAxis.tickPadding({top: 0, bottom: 0, left: 20, right:30})
  
    d3.select(element).datum(data).transition().duration(500).call(chart)
  
    nv.utils.windowResize(chart.update)
    return chart
  </code></pre>
  
  <p>I am assuming since I can't find any posted questions about this particular issue, it is probably so simple I am missing it. Thanks in advance.</p>
