Hello, I always use most detailed settings for Graph Settings. Now it is:
LiveGraph 16h/1min = 960 values x3 Graph1 2d/1min = 2880 values x30 Graph2 60d/1h = 1440 values x12.5 Graph3 750d/1d = 750 values
for unknown reasons you are using a very non-linear step between graphs (3...30...12.5) and very different values (960...2880...1440...750), (2880 is overkill, even for fullhd width), also last Graph limited to 2 years.
My suggestion is using more linear step and almost the same values: (also I suggest using Day, Week, Month, Quarter, Year - it is standard business intervals, and add Graph5):
Live 24hours/1min = 1440 values x7 Graph1 1week/10min = 1008 values x4.4 Graph2 1month/30min = 1440 values x3 Graph3 1quarter/90min = 1440 values x4 Graph4 1year/6hour = 1460 values x4 Graph5 4years/1day = 1460 values
