title: D3.js log scale stacked bar
body: <p>I am trying to construct a single column stacked bar chart with d3.js, my data array might look like this in some instances:
  [{x: 0, y:1, y0: 0}, {x: 1, y: 10, y0: 1}, {x: 2, y:2, y0: 11}]
  but in another instance it might look like this:
  [{x: 0, y:20, y0: 0}, {x: 1, y: 300, y0: 20}, {x: 2, y:2189, y0: 320}]</p>
  
  <p>I am having trouble with the log scale. The chart's height is always 150px and the rectangles for the stacked chart should not be smaller than 10px ever.</p>
