Patrike, dasboard need to add an option to change graph limits for each miner hashrate and power usage independently (yes, need to add power usage). Usually the area near zero is not useful. If your miner hasrate changes from 120 to 160 MH/s it is better to cut the 0-100 MH/s area and see the more detailed statistics for 100-180 MH/s area. If 1st miner speed is H/s and the second miner speed is MH/s the dashboard screen becomes fully useless for the first miner. That's why need independent limits for each miner. Sometimes you can not understand the real power usage without seeing statistics.
