Database to diagram

[Crimson King]

I have a database of ships and loading / discharging dates (and various other
info). Using the information from the database, is it possible to display
diagrammatically, each vessel as a "block" against the same date line with
the click of a button (basically a simple visual schedule).

You could give each ship a numerical value each day starting with a value of
1 if there is one ship on that date, a 1 and 2 if there are two ships,...

Then plot this set of numbers and dates in a chart with the dates as the
x-axis and the number as the Y-axis. I would try a stacked line plot.

You could also change the markers to little ship pictures.
