TL;DR
The x-axis labels on the production graph have "weird" decimals, due to the number of divisions not aligning well with the max value.What ?
I suggest changing the number of major tick lines in the production graph from 21 to 20.IDK if this is "best" for the 50h+ production graphs, but it's not worse, IMO. Perhaps 25 major tick lines on those makes more sense, but I'm not making multiple suggestions, here.
Image of the current situation
I can't easily produce an image of my solution, but in the image I provided, each x-axis value would be a multiple of 0.5.
For the 1 minute graph, the ticks would be multiples of 3 s.
For the 1 hour graph, the ticks would be multiples of 3 min.
For the 10 hour graph, the ticks would be multiples of 30 min.

IDK how to do this. I'm happy to edit this OP if someone corrects my ignorance.
