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

Since Highcharts 5 introduced styled mode, you can easily find the symbol elements, and change their attributes. To make the symbol square:

$(".highcharts-legend-item path").attr('stroke-width',16);
