Lines in the sand

How do we show past averages and other series on graphs?

The past often provides context for present events. Through understanding previous commonality and rarity, we throw an anchor into current tides.

Weekly reports from the Office for National Statistics show death registration counts. These figures separate into whether those deaths involve Covid-19. The disease was either an underlying cause, or contributed to that person’s death. For deaths not involving Covid-19, there was no mention on the death certificate.
