3. Charts

The Graphs screen allows you to graph various information about your diabetes on several time scales. In fact, each graph can be displayed with weekly, monthly or yearly values. It is possible to display graphs of seven different types of data:

• Blood glucose over time: displays the blood glucose measurements recorded in the logbook over the week or month and the monthly average blood glucose over the year.

• Average blood glucose by time of day: shows the average blood glucose at different times of the day.

• % time by blood glucose level: shows the percentage of time spent in each range of your blood glucose target. The red portion is time spent in hyperglycemia, the purple portion is time spent in hypoglycemia, and the green portion is time spent in your blood glucose target.

• Average Blood Sugar + Insulin: Displays two graphs, one corresponding to your daily average blood sugar (if you are viewing graphs on a weekly or monthly basis) or your monthly average blood sugar (if you are viewing graphs on a yearly basis). And the other, your daily insulin doses (if you are viewing graphs on a weekly or monthly basis) or your daily average insulin doses over each month (if you are viewing graphs over the year).

• Average Blood Sugar + Activity: Displays two graphs, one corresponding to your daily average blood sugar (if you are displaying graphs over the week or month) or your monthly average blood sugar (if you are displaying graphs over the year). And the other, your activity in steps per day (if you display the graphs over the week or month) or your activity in average daily steps over each month (if you display the graphs over the year).

• Number of times on target: Shows how many times you have been in or out of your blood sugar target based on different times of the day.

• Average Blood Sugar + Oral Medications: displays two graphs, one corresponding to your daily average blood sugar (if you are viewing graphs on a weekly or monthly basis) or your monthly average blood sugar (if you are viewing graphs on a yearly basis). And the other, your oral medication doses per day (if you are viewing graphs over the week or month) or your daily average oral medication doses over each month (if you are viewing graphs over the year).

• Postprandial blood glucose in target: shows how many times you were in or out of your postprandial blood glucose target based on different times of the day.

To change the time period over which the graphs are displayed, simply select the desired period between the graph title and the graph. To choose which graph to display, you can select the one you want by scrolling the graph selector between the date and the display period. Finally, the date at the top of the screen corresponds to the end date of the current display period. To modify it, you can press it and select the date you want thanks to the calendar or use the arrows which will modify the date by one day for the single arrows and by one month for the double arrows.
