Multiple pie-charts in the same chart with HighCharts

Question

I'm trying to draw multiple pie-charts in the same chart with HighCharts .

JSFIDDLE DEMO

I have enabled the legend for each pie-chart. Now two legends for the 2 charts are shown at the bottom ( notice that 2 items for each entry are visible in the legend ). When I click on an item of the legend it shows/hides a piece in one pie-chart...

But I want to achieve either of followings,

1. I want to have a single legend for both charts so that relevant piece of both pie-charts disappears/appears when I click on an item of the legend .

2. I want to show only one legend and disable it so that clicking doesn't hide/show pieces of pie-charts.

Anybody knows a way to achieve either?

Thank you in advance...

Answer 1

I have added the below code to detect the legend item clicked.

function(chart) {
        $(chart.series[0].data).each(function(i, e) {
            e.legendItem.on('click', function(event) {
                var legendItem=e.name;

                event.stopPropagation();

                $(chart.series).each(function(j,f){
                       $(this.data).each(function(k,z){
                           if(z.name==legendItem)
                           {
                               if(z.visible)
                               {
                                   z.setVisible(false);
                               }
                               else
                               {
                                   z.setVisible(true);
                               }
                           }
                       });
                });

            });
        });
    }
