You can wrap exportChart method and set showInLegend property to false on invisible series:

var H = Highcharts;

H.wrap(H.Chart.prototype, 'exportChart', function(proceed, exportingOptions) {
    var series = this.series;

    Highcharts.each(series, function(s) {
        if (s.visible) {
            s.update({
                showInLegend: true
            }, false);
        } else {
            s.update({
                showInLegend: false
            }, false);
        }
    });

    // which are sliced off this function's arguments
    proceed.apply(this, Array.prototype.slice.call(arguments, 1));

    Highcharts.each(series, function(s) {
        s.update({
            showInLegend: true
        }, false);
    });

    this.redraw();
});

Try this:

series: [{
            showInLegend: false,
            name: 'Series',
            data: value                
        }]
