It would be helpful if you would provide in your description what
you mean by "don't plot well".
I am going to guess that you are referring to the fact that the range
of the vertical axis runs from 0.86 to 1.01. This can be fixed by
using the option PlotRange as follows:
Plot[t - (t - 1) UnitStep[t - 1], {t, 0, 5}, PlotRange -> All]
The algorithms that the kernel uses to select a vertical plot
range work for most cases, but functions with jumps like this
sometimes give strange results.
