It makes sense to have a logarithmic rather than linear scale where you want to be able to read off values reasonably accurately at different scales, accommodated on a single graph. For example sometimes we are interested in slight overloads that trip in the order of 1000s. If time was on a linear scale of 0-1000, that graph would be useless for reading of values that occur in in 10s or less for example.
