Single legend representing multiple series

[vinita]

I can use showInLegend to hide legends when there are multiple series. Is it possible to represent all the series by single legend? Thank you!

Hello,

Yes, you can use linkedTo property to link some series with others.

How can I make the single legend hover highlight multiple series as well?

Hi there,
Thank you for contacting us.
The functionality that you described is not available in Highcharts by default. However, a simple core code modification makes it work.
Live demo: https://jsfiddle.net/BlackLabel/L83hn1wd/

The only two pieces I've added are:

Code: Select all

             if (item.linkedSeries[0]) {
               item.linkedSeries[0].setState('hover')
             }

&

Code: Select all

             if (item.linkedSeries[0]) {
               item.linkedSeries[0].setState()
             }

Please let us know if you have any further questions.
Best regards!
