Value scale––
How the heatmap value is calculatedOne cell represents one calendar day and one ten-minute window. Its value is the median of the quality-filtered measurements in that window. The backend setting currently includes high- and medium-grade measurements; unusable measurements are always excluded. With at least 20 cells, the colour scale spans the 2nd to 98th percentile so individual outliers do not dominate. Values outside that range use the end colours. Hover or click shows the individual measurement closest to the cell median.
