x-axis:
linear, goes from 0 on the left to 100 on the right.
at point n in the x-axis, you have a greater age than n% of all existing nations in nationstates
basically percentile for age
age is computed as current time - firstlogin of nation
y-axis:
linear, goes from 0 on the bottom to 100 on the top.
at point v on the axis, you have spent v% of time since the creating of your nation in existance, that is, not in cte.
basically goes from always cte to never cte
intensity:
goes from blue (none) to red (highest).
this'll be elaborated on
intensity is proportional to the number of nations in each pixel/category
same as above but with nations from 97.5 to 100 on the y-axis removed in order to show cells better
same as above two but intensity is now squared
compensates for non-existant nations
that is, a nation which is 10 on the y-axis, or existing 10% of the time, is multiplied by 10, because for every nation in that category there are 9 more that we don't see
same as above, values squared
first 29 days of nation are immune to cte because they haven't had 29 days to be inactive. this chart subtracts those 29 days to show a clearer picture. image compensates for missing nations and squares values
same as above, intensity not squared and first row removed
just as a note, nations which cte and do not return again are not counted in this chart for obvious reasons
