[Eeglablist] Lines connecting electrodes in topoplot

[m.haverkate at student.utwente.nl]

Hello,
 
I'm doing research on phase synchrony between different electrodes. I would like to highlight electrodes with a significant phase locking value. How can I draw lines between two electrode positions in a topoplot?
 
Thanks,
