Confused about how the graph works
 

I posted twice on 0ctober 1st. I entered 139 for before breakfast and 121 for after lunch. The graph shows a red score of about 145 also. I did not enter that score. Why is it on the graph?

Red High @ 139
Magenta Average @ 130
Blue Low @ 121

Please reveiw the graph again, the red line should be below the 140 line. Please be advised that the graph will get better accuracy, with more data input, than the two points. I hope the information helps.

It is below 140. My question is why is that red line score there because I did not enter it.

I only enter two scores, however three show on the graph.

The red line should be the "High Number" (139), as referenced in the graph legend at the top of the graph. You will always have three lines the App averages the data that you have put in.
