At a glance
The leftmost portion of the At a Glance section shows you the percentage increase or decrease of usage over the prior week. The middle portion shows you exactly how much water you consumed during the last seven days compared to what you used during the seven days before that. Your average daily use is also shown.
The bar graph on the right shows even more detail. Hover your cursor over the bars to see how much water you used on a given day and compare it to the same day of the previous week. The horizontal green line shows your 30-day average use.
