This graph is displayed by clicking the button, or selecting it from the View menu. It shows the distribution of readings by day of the week.
The numbers along the left edge of the graph are blood glucose values. The upper limit of the graph adjusts automatically to accommodate the range of readings to display. The horizontal dotted lines show the target range. The blue line and numbers represent the average readings for each day. The number of readings for each day is shown along the bottom of the window.
This graph can be resized by dragging an edge or corner of the window with the mouse.
