title: Highcharts stream graph - how to make 1:1 scale by Y axis?
body: <p>Here is my code - <a href="https://jsfiddle.net/rxqpt8u4/1/" rel="nofollow noreferrer">https://jsfiddle.net/rxqpt8u4/1/</a></p>
  
  <pre><code>var colors = Highcharts.getOptions().colors;
  Highcharts.chart('container', {
  
      chart: {
          type: 'streamgraph',
          marginBottom: 30,
          zoomType: 'x'
      },
  
  
     yAxis: {
  
          min:0           
      },  
      // Data parsed with olympic-medals.node.js
      series: [
      {
          "name": "Austria",
          "data": [
              2, 3, 4, 5, 5, 6, 6, 6, 7
          ]
      }]
  
  });
  </code></pre>
  
  <p>Can't understand why values dont scales 1:1.
  Instead of that, they scale 0.5:1.
  Please advise.</p>
