title: dc.js cap ordinal bar chart
body: <p><a href="http://nickqizhu.github.io/dc.js/" rel="nofollow noreferrer">dc.js</a> has a <a href="https://github.com/dc-js/dc.js/blob/master/web/docs/api-latest.md#cap-mixin" rel="nofollow noreferrer">Cap mixin</a> which allows one to limit the number of groups and display the remainder in an "others" group. How does one access this behavior or exclude the remainder in a bar chart?</p>
  
  <p>I am using a bar chart as I want to show a top 5 with stacked data. For example, the top 10 car manufacturers based on the total of fleet and private sales (in separate stacks). I am using a function to dynamically generate 5 ordinals (i.e. car manufacturers) for the x axis in the order that I want, and the graph generates nearly as expected. However, a separate bar containing the values that don't fit into one of the x values is placed at the start of the graph.</p>
  
  <p>I've added a snapshot of the chart below. Note that I've rotated it with renderlet so it's on its side.</p>
  
  <p>How do I remove the extraneous bar (at the top)?</p>
  
  <p>If not possible, I may contemplate using two row charts side by side with one flipped so that the origin is on the right.</p>
