This is an example that does that, plus a variety of other things with legend items and checkboxes, using a series of external controls:

http://jsfiddle.net/simo/57SR9/94/

function:

$('#checkAll').click(function(){
    for(i=0; i < chart.series.length; i++) {
        if(chart.series[i].selected == false){
            chart.series[i].select();
            showSeries.call(chart.series[i], {checked: true});
        }
    }
});

您可以遍历图表中的每个系列并调用show()或hide()函数，具体取决于您想要做什么。此解决方案与之前的答案类似，但使用show/hide函数调用

i = 0;

while (i < chart.series.length) {
    if (chart.series[i].visible === false) { // here you can filter the visible series
        chart.series[i].select();
        chart.series[i].show(); // here you can call hide()
        i++;
        return;
    }
}

You can use something like this:

 var legendLeft = $j('<div>')
               .css({
                   width: 160,
                   maxHeight: 210,
                   padding: 10,
                   position: 'absolute',
                   overflow: 'auto',
                   right: 500,
                   top: 380,
                   borderRadius: options.borderRadius
               })
               .appendTo(chart.container);

           var legendRight = $j('<div>') .css({
                width: 260,
                maxHeight: 210,
                padding: 10,
                position: 'absolute',
                overflow: 'auto',
                right: 165,
                top: 383,
                borderRadius: options.borderRadius
           }).appendTo(chart.container);
