markerBorderThickness: Number

Sets the thickness of the Marker’s Border in pixels.

Default: 0
Example: 4, 7..
Notes
  • Set markerBorderColor to a different color than markerColor to see border appear around marker.
  • There is no border in Marker Type “cross”, hence markerBorderThickness doesn’t apply when markerType is “cross”
