Chart showing date and names on a time axis

Hi guys,

I'm trying to create a chart/matrix where you should be able to see a list of names on the y-axis and a time line (dates) on the x-axis. Each name (y-axis) should have a "marker" along the x-axis aligned with the name, where a date is displayed on the side of the marker.

The whole idea is to create a chart (or similar) where you can easily see when you have last contacted/communicated with a certain person.

I've attached a "mock up" of how I suggest it can look, but I've had no luck what so ever in creating this on my own.

Anyone got any bright ideas?
