Fig 2. Cumulative distribution functions (CDF) of daily tweet volumes (A, C, E) and Q-Q plots of logarithms of daily tweet volumes for each political party (B, D, F).

Fig 2

Each volume in CDF is normalized by the average ⟨V⟩. (A) CDF of daily tweet volume of Euro14. (B) Q-Q plot of Euro14. (C) CDF of daily tweet volume of Italy13. (D) Q-Q plot of Italy13. (E) CDF of daily tweet volume in Bulgaria13. (f) Q-Q plot in Bulgaria13. Note that Q-Q plot is for logarithm of daily tweet volume. Theoretical quantile in the Q-Q plot is based on normal distribution. Thus if the points in the Q-Q plot lie on y = x line, the daily tweet volume follows a log-normal distribution since the logarithm of the volume follow a normal distribution.
