Highcharts donut legend toggle

问题:

Im using a highchart pie chart to make Donut chart. The problem is when I click on legend to toggle series it only affects the clicked serie. I want to also toggle related sub series. I have tried LegenditemClick event and legendIndex , but no success so far. Here example for chart: http://jsfiddle.net/safarov/PgpRv/ When you click "facebook legend" for example, only inner pie hide.

Any help will be appreciated

You need to set ids for inner and outer rings. Then common it by legendItemClick and search correct point by id.

legendItemClick: function () {
                    var id = this.id,
                        data = this.series.chart.series[0].data;
                    $.each(data, function (i, point) {

                        if (point.parentId == id) {
                            if(point.visible)
                                point.setVisible(false);
                            else
                                point.setVisible(true);
                        }

                    });
                }
