Where are the bar graphs that show 30 days of data?
There are two ways to getting to these bar graphs mapped out below. Both are viable options.
Tap on the TITLE BAR of the LOG section i.e "HYDRATION"
You should now see a bar graph with 30-days of hydration data.
On the main Score graphic, tap on the section of the score you'd like to see in detail.
From there you will be able to see a graph of your data as well as the color guidelines for that section, i.e. how many minutes of cardio with constitute green/yellow/red.
