[Fix request] Graph zoom during training

[Xabab]

Currently Y axis is from 0 to some value. The problem arises, when the difference in loss between start and finish of the training is not that big, for example from 3.2 to 2.5, it is very hard to see the slope of the curve. It would be more convenient to have Y axis from the lowest loss value to the largest value and not from the 0
