Bar graph with events happening throughout the day.

Hello there!

I'll try to explain this as well as I can.
I have two types of events, and each event has its start and end time. For example (red 10.15-11.07; blue 11.55-12.30; blue 15.33-17.22; etc)
What I need is a type of bar graph, where the whole bar would be 24h long (left end is 00.00, right end is 23.59), and these events would be colorized on this bar.
Then there should be different bars on top of each other, representing different days.

How could this be done? I found something similar that I looked for, but it was restricted to one event per day.
I can't post here, but if anyone wants I can send a drawing of what I want the chart to look like.

So, if anybody knows how to approach this or how is the most efficient way to lay out the data, I'll be thankful.
