          @brief Shows evolution of order parameter (level of global synchronization in the network).
          
          @param[in] sync_output_dynamic (sync_dynamic): Output dynamic of the Sync network whose evolution of global synchronization should be visualized.
          @param[in] start_iteration (uint): The first iteration that is used for calculation, if 'None' then the first is used
          @param[in] stop_iteration (uint): The last iteration that is used for calculation, if 'None' then the last is used.
