How to represent timed events on Matlab?

Hi, I have a series of event in cells of this type:

serie 1: 24x3

serie 2: 12x3

serie 3: 15x3

where column are start, duration and stop (start + duration) of an event (24 events for serie 1, 12 for serie 2...) with gaps between starts and end. I would like to represent them on a timeline, i.e. to have the time on x-axis and 3 sets of data represented e.g. with segments on y axis.

How can I do it with Matlab?

Thanks
