You can disable default legend and create your own as HTML. Then you can control which point should be or not displayed.

Example: http://jsfiddle.net/N3KAC/1/

$legend = $('#customLegend');

    $.each(chart.series[0].data, function (j, data) {

        $legend.append('<div class="item"><div class="symbol" style="background-color:'+data.color+'"></div><div class="serieName" id="">' + data.name + '</div></div>');

    });

    $('#customLegend .item').click(function(){
        var inx = $(this).index(),
            point = chart.series[0].data[inx];

        if(point.visible)
            point.setVisible(false);
        else
            point.setVisible(true);
    });
