jqplot : how to display value from an array in a highlighter

I have a chart which represent a number of elements per month. I would like to show the list of those elements in my highlighter. The data I received are the following : 

[["2013-12-01", 2, ["First element", "Second element"]], ["2014-01-01", 0, []]]

Actually, I'm able to display in my tooltip the number of element I have, but I don't know how to display the list of the elements. My highlighter code is the following : 

highlighter: {
                tooltipAxes: 'y',
                formatString:'%u elements',
                showLabel: true,
                sizeAdjust: 7.5,
                  },

It effectively display the number of elements. At the end, I would like to have something like this as an html code in my tooltip : 

2 elements : <br>
<table><tr><td>First element</td><td> Second element</td></tr></table>

One solution could be to generate the html code in my data but I would like to separate formatting and data generation. Any "clean" solution?

Thanks in advance!

Looking at the api for the jqplot.highlighter.js plugin, it doesn't appear to give you that level of control (it would be nice if it had a formatter callback). So, I'd just drop the plugin all together and code it yourself using the jqplotDataHighlight and jqplotDataUnhighlight events:

    $('#chart2').bind('jqplotDataHighlight', 
        function (ev, seriesIndex, pointIndex, data) {
            var aList = myData[pointIndex][2];
            $('#tooltip').html(aList.join('<br/>'));
            $('#tooltip').css('display','block');
        }
    );

    $('#chart2').bind('jqplotDataUnhighlight', 
        function (ev) {
            $('#tooltip').css('display','none');
        }
    );

Here's a working example.
