Hello, I would like to represent the presence of actors on screen at different times using the plotly gantt chart. The timestamps are in seconds, which I would like to represent along the xaxis, and if possible, use for the time information in the hovertext. So far, I’ve only managed to remove the…

Hi @barnold , Welcome to the forums! This sounds like an interesting plot. Could you share a small dataset (made up is fine) so that you’re current example can be reproduced by other folks? It may end up being easier to do this starting with a standard bar trace rather than starting with the gant…
