title: How to set y-axis to fixed range in rickshaw?
body: <p>I have data where most of the values are in range 41-44, but occasionally there are peaks to 150-350, so y-axis is automatically scaled to 0-350 and chart is simply unreadable. </p>
  
  <p>How to set fixed min and max for y-axis? I know that some values will be "above" chart, but that is not a problem.</p>
  
  <p><a href="http://kartstat.com/graph/ironman_siedlce.html" rel="noreferrer">Here is my chart</a></p>
  
  <p><strong>EDIT:</strong> alternatively I want to enable zooming in this graph which would be even better, any idea how to do this?</p>
  
  <p><strong>EDIT2:</strong> or maybe you can suggest other simple charting library with enabling/disabling lines, zooming &amp; panning?</p>
