same colour. In Fig. 4.3, events are divided into two categories: weekdays
and holidays. Events on weekdays have been shown in light blue and
events on holidays have been shown in pink. Thus, we can understand the
features of the events in detail by visualizing the attributes of these events.
Fig. 4.3. Events on weekdays and holidays are distinguished by colour.
Light blue represents weekdays and pink represents holidays.
Representation of Additional Information
In Fig. 4.1, events are represented by circles on a two-dimensional plane.
Additional lines make the visualization more detailed and/or clearer.
ChronoView has some ambiguity of representation, because it may assign
the same position to some events with different time-stamps. We have
considered a way of avoiding this ambiguity.
