Figure 1 - Graph
Diabetes:M provides a lot of statistics in form of diagrams, graphs and charts. You can view your collected data visually and understand it better.

Graph

This screen displays all the entries as a graph. You can scroll it left and right to see a particular time interval depending on the selected scale.
* The graph is important because it shows you all viable information distributed by short periods of time. You can easily find patterns in your daily medications/insulin intakes and your foods intakes. You can also analyze how different actions affect your body, for example exercises, insulin injections or bigger/lower food intakes.
  1. Glucose Entry
  2. Insulin injection mark
  3. Carbohydrates amount mark if present. Note that it should match the insulin mark if insulin covers the carbohydrates amount according your carbohydrates ratio for the time of the entry.
  4. Insulin activity graph. You can see the peaks of activity especially if you have multiple injections before the expiration time of the first injection.
  5. Glucose entry marked as "Fasting Glucose".
  6. Oral medications mark.
  7. Line marking the beginning of the day.
  8. Hyperglycemia glucose level. Above that value glucose readings are considered as hyperglycemia.
  9. Target Glucose levels.From highest to lowest glucose level they're shown as Hyper, Hi, Target, Low, Hypo with according horizontal lines.
  10. "Scale" changes the scale of the graph. You can select from day, week, month and year.
  11. "Time" positions the graph view at a particular time
  12. "Settings" allows you to configure which marks and elements in the graph to see.
  13. Timeline showing 0-24 hours from the day
Figure 2 - Glucose levels distribution by days periods
Charts screen shows statistical data charts. When tap on the chart (except the pie charts) it goes full screen where users can pinch or double tap to zoom in/out the chart.   

Distribution by days and chart interval selection (Figure 2)


These pie charts show your blood glucose distribution according the target limits you entered in the settings. You can select the time interval for the other charts as tapping on the corresponding pie chart. Its border will be highlighted.
They are useful because you can see easily what your glucose levels averages were in the last 7/14/30/90 days and check how you were doing in the near past.
Figure 3 - Glucose levels distribution by category
Distribution by category for the selected interval (Figure 3)


These pie charts show your blood glucose distribution per time category as night, before meal, after meal or other if the reading appears in other time. 
In those charts you can find if you have problems in some time of the day, for example if your glucose before bed was usually higher than it needs to be or you're not measuring your glucose enough in some time of the day. Such strange things about your glucose measurements can be seen easily on those charts.
Time categories are:

"Night" - between 21:00 to 07:00 in the morning
"Before" meal - 1 hour before the meal
"After" meal - 2 hours after the meal
"Other" - all other hours and categories as "Snack" and "Fasting Glucose"

Meal hours as breakfast, lunch and dinner are specified in the Settings screen.
Figure 4 - Average glucose levels overlay for distributed by hours
Glucose Overlay for the selected interval (Figure 4)


This chart shows the distribution of all the glucose readings for the selected interval during 24 hours. This helps to see for which hours you don't have enough information. Usually all the readings are clustered around the meal hours but it is good to know what are the values for our blood glucose during the whole day. You can also find some patterns in some hours of low/high glucose levels through the day.
Figure 5 - Average glucose levels overlay for distributed by days of the week
Glucose Week Overlay for the selected interval (Figure 5)


This chart shows the distribution of all the glucose readings for the selected interval during the week. It can help you find strange glucose level readings by day, for example you may find out some day of the week you have lower/higher glucose levels and you can than think about why this happens and find some actions or events in that day that affect your glucose levels.

For every day the averages are calculated for the first and the second half of the day. For every day there are two averages from 12:00 am to 12:00 pm and from 12:00 pm to 12:00 am.
Figure 6 - Average glucose levels overlay for distributed by day
Glucose History for the selected interval (Figure 6)


This chart shows the history of all the glucose readings for the selected interval. Averages are calculated per day. You can find out how some events affected your diabetes management, for example if you were on a vacation for a few days, you can see those days averages here.
Figure 7 - Metabolic control (average glucose/average glucose deviations)
Metabolic control for the selected period (Figure 7)


This chart shows the glucose variability and average daily glucose. It tells you if your glucose is varying too much and if your daily glucose levels are normal. In the best scenario most of the dots (readings) should be in the inner circle.
If most of the readings are in the inner and outer circle it means that your glucose was stable and didn't vary too much.
Figure 8 - Insulin daily totals (by type, including correction)
Insulin daily totals for the selected interval (Figure 8)


This chart shows the insulin daily totals for the selected interval. Bars show the ratio between basal (orange), bolus (light blue) and correction bolus (dark blue) insulin totals. 
It can help you find out if your insulin injections are similar through the day or if you have too many corrections, which may be a bad sign.

Description

  1. Orange - used basal (slow acting insulin) for the period
  2. Light blue - used bolus (fast insulin) for the period
  3. Dark blue - calculated additional bolus, for example if your blood glucose was above normal and the app calculated that you need more than usual bolus insulin
Figure 9 - Carbohydrates to bolus insulin distribution by category
Carbohydrates and insulin averages by meal for the selected interval (Figure 9)


This chart shows the average insulin and carbohydrates by periods of the day - night, breakfast, lunch, dinner, before bed.
It can help you to see your average carbohydrates intake and your average insulin intakes by time of the day. This way you can find how different carbohydrates amounts affect your insulin intakes and the opposite.
Figure 10 - Food calories and nutritions distribution
Food nutrition data and grams intake for the selected interval (Figure 10)


This chart shows carbohydrates (green), proteins (orange) and fats (purple) of the food you take over the selected period of time, distributed by times of the day. Also it shows calories count (the black line with dots), needed calories and food's weight.
Figure 11 - Blood glucose deviation distribution by meals categories
Averages by meal for the selected interval (Figure 11)


This chart shows the minimum, maximum and average values of blood glucose per meal categories. The chart can help you find if you have too big deviations of the blood glucose during the day. Usually you may have good average glucose values, but if you have big deviations it's not a good sign for your diabetes management. 
Description
  1. Highest measured value for the selected interval and meal category
  2. Average value of all readings for the selected interval and meal category
  3. Lowest measured value for the selected interval and meal category
  4. Zone "Before" meal
  5. Zone "After" meal
Figure 12 - Insulin sensitivity/Carbohydrates ratio averages by hour
Insulin Sensitivity/Carbohydrate Ratio (Figure 12)


This chart shows calculated carbohydrate ratio and insulin sensitivity based by the information during the selected interval. Diabetes:M tries to identify patterns in the data you entered with which it can calculate some insulin sensitivity and carbohydrates ratio. If you have enough entered and correct data, those values should almost match your insulin sensitivity and carbohydrates ratio.
Description 
  1. Insulin sensitivity bar
  2. Carbohydrate ratio bar
  3. Average value calculated for the hour
  4. Count of the successful calculations for the hour. The hour average is calculated using these values

In the chart description at the bottom of the chart you can see the total averages for these values based by all successful calculations.

Calculation basics

To calculate carbohydrate ratio successfully there must be a glucose reading, insulin dose and carbohydrate entry and there must be at least one glucose reading during the second, third or fourth hour after the first reading. 

To calculate insulin sensitivity successfully there must be a glucose reading below or above the target and insulin dose entry but NOT a carbohydrate entry. There must be at least one glucose reading during the third, fourth or fifth hour after the first reading.

Important
: These values could be wrong if there are not appropriate data patterns found and not enough successful calculations are made for some hours. Using these values for correcting insulin doses must be done with extreme caution and increased blood glucose measuring.
