HighCharts: One Legend, Two Charts

Question

I have four different HighChart spline diagrams. All contain six episodes representing the six states of New England. I want to click on any legend and hide / show this series in all diagrams. I tried legendclickitem but can't make it affect both graphs. This is what I am asking if so you can point me in the right direction, thanks.

Answer:

Using the Paweł FusIn code and to keep the legend in each diagram, I used the following code. You can click on any legend item and update all charts.

plotOptions: {
series: {
events: {
legendItemClick: function(event) {
if (this.visible) {
$('#container1').highcharts().series[this.index].hide(); 
$('#container2').highcharts().series[this.index].hide(); 
$('#container3').highcharts().series[this.index].hide(); 
$('#container4').highcharts().series[this.index].hide(); 
} 
else {
$('#container1').highcharts().series[this.index].show(); 
$('#container2').highcharts().series[this.index].show(); 
$('#container3').highcharts().series[this.index].show(); 
$('#container4').highcharts().series[this.index].show();
}
return false;
}
}
}

    legend: {

    series: [{

$('#container2').highcharts({
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']

    plotOptions: {
        series: {

                legendItemClick: function (event) {
                    var XYZ = $('#container1').highcharts(),
                        series = XYZ.get(this.options.id); //get corresponding series

                    if (series) {
                        if (this.visible) {
                            series.hide();
                        } else {
                            series.show();
                        }
                    }
                }
            }
        }
    },

    series: [{
        id: 'someId',
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
