This graph is displayed by clicking the button, or selecting it from the View menu. It shows the range of readings taken each day and is similar to the graph shown by GlucoBase PDA.
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 vertical bands represent seven day periods beginning on Sunday. The date under each band is for the Sunday of that week.
This graph can be resized by dragging an edge or corner of the window with the mouse. Making the window wider will allow more readings to be displayed.
