By periodization the history after Islamic revolution into four periods, i.e. first period (1979-82), second period (1982-98), third period (1988-2006), fourth period (2006-2013), the collected data show that the amount of democracy indicators has fluctuated over time except the period of 1979-1982, but, the fluctuation has leaned to up, not down.
