If the mouse cursor is hovered over any one of the red bullet points on the graph, a blue information box will give the number of days the item has been drying, and the cumulative loss of water (in grams weight, and as a percentage of the original weight), at that bullet point on the graph. The exact date and weight at that bullet point are displayed (in blue information boxes), where the blue cursor lines intersect with the horizontal (Time/Dates) and vertical (Weight) graph axes.
