Abstract: A computing device with a touch sensitive display is used to graphically display point-of-care diagnostic health data values (e.g., blood pressure or blood glucose readings) in a calendar view. The user performs gestures on the touch sensitive display to interact with the calendar to select one or more series of the data from specific calendar days. Computations are performed on the selected series to summarize the data. Data from one or multiple different series are organized, summarized and displayed in a graphical, numerical, or tabular format to enable comparisons between series, and facilitate understanding of data and data trends for diagnostic and treatment decisions.
