Highcharts: Make the legend symbol a square or rectangle

Question

I am trying to Make the legend symbol a square or rectangle for a line graph. Example

Answer 1

For rectangular legend we need to set squareSymbol: false.

Highcharts.chart('container', {
    chart: {
       type: 'column'
    },

    title: {
       text: 'Round legend symbols'
    },

    xAxis: {
       categories: ['Jan', 'Feb', 'Mar', 'Apr']
    },

    legend: {
       symbolWidth: 16,
       symbolRadius: 0,
       squareSymbol: false
    },

    series: [{
        data: [1, 3, 2, 4]
    }, {
        data: [6, 4, 5, 3]
    }, {
        data: [2, 7, 6, 5]
    }]

});

<div id="container" style="height: 400px"></div>
