omnivore.csv from markers to lines

[alf4all]

I have a .csv file with time, latitude and longitude information.
With: omnivore.csv('csv/5935br27gps_050.csv').addTo(mymap); I can add the GPS-positions with some customizing as markers on my map
( see: http://alf4all.demon.nl/engineering/topics/projects/iot/leaflet/test_04.htm ).
But... How to add a polyline between the track-points? Can this be integrated in the .on('ready',function(layer){...});?
Thanks and regards...
