The interval range sets the number of days or months for graphing connecting lines between data points on a patient's graph. Days are used for graphs plotted in months (such as 0-24 months); months are used for graphs plotted in years (such as 2-20 years). For example, if the interval range on a graph plotted in months is 60 days, the graph displays a connecting line between data points entered within 60 days.
