Line — median, dark band — 25–75% of readings, light band — 5–95%. Green zone — target range.
The percentage on the right is that day's time in range.

What the numbers mean. Targets follow the international consensus (ATTD 2019) for most adults with type 1 and type 2 diabetes: time in range 70–180 mg/dL above 70%, below 70 under 4%, below 54 under 1%, glucose variability (CV) at or below 36%. Targets differ for pregnancy, children and older adults — check with your doctor.
The AGP (Ambulatory Glucose Profile) is the standard one-page report for continuous glucose monitoring data. All days are overlaid onto a single 24 hours, so you can see when glucose usually runs high or low. It is what endocrinologists look at.
The share of time glucose stayed within 70–180 mg/dL (3.9–10.0 mmol/L). The target for most adults is above 70%, roughly 17 hours a day.
The Glucose Management Indicator — an HbA1c-like estimate calculated from your mean sensor glucose (Bergenstal 2018). It can differ from your lab HbA1c, and that is normal.
