Event-series visualization

Hallo! Iam trying to find a specific graph to visualize an event series! I would like to find a graph that consists of a horizontal bar with vertical bars inside it which indicate the instants the event happened! Thanks a lot!

You won't "find" it. You can write it, as just some calls to patch, for example.

Thanks for your answer! I am trying to bypass this problem with the command:

bar(y,'stacked')

but I dont know how to make the intermediate lines of the each bar distinguishable.

@Panos Ale: At least to me it is not clear what you exactly want. Can you draw an example? Posting an image might be useful also.
