General components and details of historySkyline:

(a) time runs from left to right
(b) each bird is a piece of data about the city's population
(c) above the horizon line, amount of changes for each year on the whole set of edifices. (c1, red) functional changes; (c2, black) destructive changes; (c3, blue vertical bars) morphological changes
(d) amount of sources used to document the changes
(e) military events that impacted the city - those that lasted several years are represented by an arc that joins two dots

(f) rectangles on the horizon line: kingdom's rulers
(g) little squares correspond to punctual events that occured in the city (mouseover to identify them)
(h) For each time interval (i.e. durations of each transformation of each edifice), certainty of dating of the left and right bounds are figured using a “street lamp-like” shape. Certainty is formalised as a 3-levels lexical scale, the image below shows, from left to right, levels of certainty in descending order (the more"certain" is on the left)

Different shapes are used to represent military events on line (e). From left to right, siege, invasion, occupation, march, assault.


Colours represent the army involved
From left to right, Hungarians, Swedes, Austrians, Germans, Czechs, Mongols, Poles.
