title: How to link a chart axis to a chart series using the Shinobi iOS SDK?
body: <p>I added a secondary axis to my chart using <code>addYAxis:(SChartAxis *)newYAxis</code>. How do I get the second series linked to the new axis?</p>
  
  <p>I found <code>(BOOL)isLinkedToSeries:(SChartSeries *)series</code> in SChartAxis.h.  But how do I create the initial link?</p>
