How to access legendSymbols and change their shape in HighCharts

Question

I have a line chart with markers disabled. The legendSymbol is currently a line. I would like to show the symbol as a square. Any pointers?

Answer 1

You can use two series (one normal and one fake) with defined custom symbol. First should be hidden in legend. Then only what you need is use legendItemClick and call action.
