Blood GlucoseTrend line...Date and Time Help ...What a MESS!!!

[Fran Munschauer]

Hi, I just don't understand all of the jargon but have made a graph to list BG values with each test at a certain time..The date and time area was fine until last week but don't know what happened..I tried to remove the year to lessen the many numbers at the bottom. Also, in reviewing and re-reviewing trend lines to sort of get an idea if changing Insulin lowers the Blood glucose, I chose polynomial because it looked nice and ??it seem to show that BG was lowering some..I don't like moving average...THEN, I saw that if you put R2 in the equation, the number closest  to 1 is good??? Mine says .2. I don't know how to fix this.In Addition, when trying linear or exponential, the trendline simply goes up over time?? I don't get it. I just want an overall line to let me know if the Blood Glucose is improving..I am using polynomial at this time because the others don't make sense to me. I am sorry for my lack of reasonable understanding..Any help would be greatly appreciated.Thanks for reading...Fran
