Add item to Highcharts legend?

Question

Is it possible to add an item to the Highcharts legend?

I have added a custom marker at a specific point in my line chart and would like to explain to the user what this marker indicates, so ideally I would add this as an additional item to the legend area.

Answer 1

The easiest way is to add that custom marker as a separate series, instead of within the original series.

{
 name: 'Special Point',
 marker: { enabled: true },
 data: [[4,9]] 
}
