# plotOptions.pyramid.linkedTo

The id of another series to link to. Additionally, the value can be ":previous" to link to the previous series. When two series are linked, only the first one appears in the legend. Toggling the visibility of this also toggles the linked series.

If master series uses data sorting and linked series does not have its own sorting definition, the linked series will be sorted in the same order as the master one.
