/**

|
|
* Together with [gapSize](plotOptions.series.gapSize), this option
|
||
|
|
* defines where to draw gaps in the graph.
|
||
|
|
*
|
||
|
|
* When the `gapUnit` is `"relative"` (default), a gap size of 5
|
||
|
|
* means that if the distance between two points is greater than
|
||
|
|
* 5 times that of the two closest points, the graph will be broken.
|
||
|
|
*
|
||
|
|
* When the `gapUnit` is `"value"`, the gap is based on absolute
|
||
|
|
* axis values, which on a datetime axis is milliseconds. This also
|
||
|
|
* applies to the navigator series that inherits gap options from
|
||
|
|
* the base series.
