Markers in Gantt Chart


I’m new to plotly and I’m creating a gantt chart using px.timeline. There are 3 categories of data in my dataset, a normal task with a start and end time, and two types of task where the start and end time are same. I want the normal task to be a rectangle (which is how it is being plot) and the other two tasks to have a hourglass marker and a triangle marker instead of a very thin line ?

This is how my data looks :
data = [dict(Task=’’, start=’’, end=’’, color=’’, shape=’<rect, hour, tri>’)]

Is there any way I can achieve this ?

Thanks :slight_smile:
