Tidepool Views: CGM Trends
Dig deeper into your data, find more meaningful insights, identify and understand where the highs and lows in your data are coming from, and have more informed and hopefully more productive conversations with your care team.
Tidepool shows you trends from your continuous glucose monitor (CGM) data in 30-minute segments that summarize the days in view.
- Median. The green, purple, or red box toward the center of each 30-minute segment is your median glucose value for that part of the day. That shows you where the middle of your glucose range has been.
- Half your readings. The darker gray above and below the median shows you where ½ of your glucose values have been.
- Most of your readings. The lighter gray, in combination with the darker gray, shows you where most of your glucose
values. Specifically, 80% of your glucose values for each 30-minute part of the day.
Tip: If you want to focus on these readings, uncheck the other boxes at the bottom (except “50% of Readings”).
- Peaks and Valleys. Your highest highs and lowest lows generally are not trends, but they can highlight interesting events. The boxes at the top and bottom of the bar show you where highest 10% and lowest 10% of glucose values are. Use your mouse to hover one and reveal CGM traces.
Tip: If you want to see where you glucose values are most of the time, but ignore the highest highs and lowest lows, uncheck the “100% of Readings” checkbox at the bottom.
Everyone’s trends are different. As described above, you can toggle on and off parts of the graph to find the trends most relevant to you.
- 100% of readings includes all data uploaded. Represented by the outer, clear boxes on your trends view
- 80% of readings includes 80% of data uploaded, based on the median (average) of your data. Represented by the inner, light gray boxes on your trends view.
- 50% of readings includes 50% of data uploaded, based on the median (average) of your data. Represented by the inner, dark gray boxes on your trends view.

Reveal daily CGM lines by hovering over any segment of the data bar. Clicking on one of those CGM (or BGM) data points will take you to the Daily View so you can see notes, boluses, and basals for that day.
6. CGM to BG Meter.
Switch your data source between your blood glucose meter (BGM) and continuous glucose monitor (CGM). The same date and day configuration apply to either view. Learn more about our BGM Trends View here.
7. Changing Dates.
Use the left and right arrows to adjust date range for data analysis. The time period in view will shift by the same number of weeks that are in view the number of days selected (see #3 above). To view your most recent data, select the icon next to the right arrow.
