<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>  <script src="https://code.highcharts.com/highcharts.js"></script>  <script src="https://code.highcharts.com/modules/exporting.js"></script>  <script src= "ag.js"></script>  <div id="light" style="min-width: 310px; height: 400px; left:10px"></div>  <div id="temp&humid" style="min-width: 310px; height: 400px; left:10px"></div>

you doing following:

series:[{     yaxis:1,    },   {     yaxis:2,   }]

the problem axes start indexing @ 0. index set temperature axis 2 not work because there no axis 2. in demo there 3 axes, why works these definitions.
