  Temporal offsets between the time series of solar activity indicators provide
important clues regarding the physical processes responsible for the cyclic
variability in the solar atmosphere. Hysteresis patterns generated between any
two indicators were popularly used to study their morphological features and
further to understand their inter relationships. We use time series of
different solar indicators to understand the possible cause-and-effect criteria
between their respective source regions. Sensitivity of the upper atmosphere to
the activity underneath might play an important role in introducing different
evolutionary patterns in the profiles of solar indicators and in turn cause
temporal offsets between them. Limitations in the observations may also cause
relative shifts in the time series.
