I would suggest for a more precise GH/s marks, because the current are quite inaccurate. On one of the pictures, the upper 3GH/s mark is equivalent to 3.1GH/s and the lower 4GH/s mark is equivalent to 3.6GH/s (and I guess it is the same for the others too) so I suggest they should be labeled 3.1GH/s and 3.6GH/s or get synced to 3 and 3.5. On the other picture you simply have four 2GH marks when only the upper two are above 2GH, the lower two are lower than 2GH which is misleading.

And I wanna suggest a change in the time format and tilt below the graph. The format it HH:MM:SS when clearly it never uses the seconds. They can safely be removed and also I dont see why there needs to be tilt so that every time we have to tilt our heads xD. There is enough space to fit the time without a tilt and it will be even better if the second are removed. Thanks in advance.
