how do you create a link on highcharts to open up

问题:

I am creating charts with highcharts. I like to put a link or button in a chart (possibley left-top corner) and when clicked, I like to call a function that shows another chart in a pop up window. Basically how they do it in highchart demo site. When clicke on the x on the top-right corner, go back to the orintal chart.

I was thinking about placing a subtile and place a click event to it, as below:

   subtitle: {
            text: '<span id="node42" class="node-link">by Server</span>',
            align: 'left'
            },

I have created a small java script like below:

<script type="text/javascript">


    $('node42').observe('click', function(event) {
      alert('my click handler');
    });

</script>

when clicking on the node42 link, it is not doing anything, any ideas?

I was able to do this:

subtitle: {
    useHTML: true,
    text: '<a href="#" onclick="myFunction()">by server chart</a>',
    align: 'left'
       },

and in my function

    <script type="text/javascript">
         function myFunction() {
           create the highchart syntax here
       }
  </script>
