title: amCharts, column with 2 y-axis
body: <p>I am trying to create a bar chart with an extra Y-axis that maps the %-age of the bars.</p>
  
  <p>This is the bar chart (works and shows the bars):</p>
  
  <pre><code>&lt;settings&gt;
      &lt;colors&gt;FFCC00&lt;/colors&gt;
      &lt;background&gt;
          &lt;alpha&gt;100&lt;/alpha&gt;
          &lt;border_alpha&gt;20&lt;/border_alpha&gt;
      &lt;/background&gt;
      &lt;grid&gt;
          &lt;category&gt;
              &lt;dashed&gt;1&lt;/dashed&gt;
          &lt;/category&gt;
          &lt;value&gt;
              &lt;dashed&gt;1&lt;/dashed&gt;
          &lt;/value&gt;
      &lt;/grid&gt;
      &lt;axes&gt;
          &lt;category&gt;
              &lt;width&gt;1&lt;/width&gt;
              &lt;color&gt;E7E7E7&lt;/color&gt;
          &lt;/category&gt;        
      &lt;/axes&gt;
      &lt;values&gt;
          &lt;category&gt;
              &lt;rotate&gt;42&lt;/rotate&gt;
          &lt;/category&gt;
          &lt;value&gt;
              &lt;min&gt;0&lt;/min&gt;
          &lt;/value&gt;
      &lt;/values&gt;
      &lt;depth&gt;15&lt;/depth&gt;
      &lt;column&gt;
          &lt;width&gt;85&lt;/width&gt;
          &lt;balloon_text&gt;{value} user(s)&lt;/balloon_text&gt;
          &lt;grow_time&gt;3&lt;/grow_time&gt;
      &lt;/column&gt;
      &lt;graphs&gt;
          &lt;graph gid="0"&gt;
              &lt;title&gt;Users&lt;/title&gt;
              &lt;color&gt;3333CC&lt;/color&gt;
              &lt;alpha&gt;63&lt;/alpha&gt;
          &lt;/graph&gt;
      &lt;/graphs&gt;
      &lt;labels&gt;
          &lt;label lid="0"&gt;
              &lt;text&gt;&lt;![CDATA[&lt;b&gt;User distribution&lt;/b&gt;]]&gt;&lt;/text&gt;
              &lt;y&gt;18&lt;/y&gt;
              &lt;text_color&gt;000000&lt;/text_color&gt;
              &lt;text_size&gt;13&lt;/text_size&gt;
              &lt;align&gt;center&lt;/align&gt;
          &lt;/label&gt;
      &lt;/labels&gt;
  &lt;/settings&gt;
  </code></pre>
  
  <p>Here is the data:</p>
  
  <pre><code>&lt;chart&gt;
      &lt;series&gt;
          &lt;value xid="0"&gt;Afghanistan&lt;/value&gt;
          &lt;value xid="1"&gt;Andorra&lt;/value&gt;
          &lt;value xid="2"&gt;Australia&lt;/value&gt;
          &lt;value xid="3"&gt;Burundi&lt;/value&gt;
          &lt;value xid="4"&gt;China&lt;/value&gt;
          &lt;value xid="5"&gt;Denmark&lt;/value&gt;        
      &lt;/series&gt;
      &lt;graphs&gt;
          &lt;graph gid="0"&gt;
              &lt;value xid="0"&gt;7&lt;/value&gt;
              &lt;value xid="1"&gt;3&lt;/value&gt;
              &lt;value xid="2"&gt;2&lt;/value&gt;
              &lt;value xid="3"&gt;12&lt;/value&gt;            
              &lt;value xid="4"&gt;2&lt;/value&gt;
              &lt;value xid="5"&gt;6&lt;/value&gt;            
          &lt;/graph&gt;
      &lt;/graphs&gt;
  &lt;/chart&gt;
  </code></pre>
  
  <p>What i want to do is this:
  <a href="http://www.amcharts.com/line/two-y-axes-chart/" rel="nofollow">http://www.amcharts.com/line/two-y-axes-chart/</a></p>
  
  <p>But i can't seem to be able to generate the second y-axis.
  This y-axis should have 0% at the bottom and 100% at the top. Then i will provide the data of how many % the column x has. This should be drawn as a red line.</p>
  
  <p>Any ideas?</p>
