Highlight duration offset or remove timestamps
I did an experiment in which participants listened to audio files. I would like to know
1). How can I highlight the offset of the audio file in the plots, i.e. mark the point in time at which listeners will have heard the audio file?
Since this might lead to potentially messy plots, perhaps a better alternative would be to remove timestamps before that time, hence question two:
2). How can I remove all timestamps in the trajectories that occur before the audio file has completed playing?
I assume 2). is also a bit tricky, as the duration of the audio file is different for each of the items.
