The following simple code generates a flawed plot:
f[t_] := UnitStep[t - 14.1] + UnitStep[t - 14.5] + UnitStep[t - 14.9]
Plot[f[t], t, 0, 16, Filling -> Axis, Exclusions -> None]
I never expected part of the connection is slanted. Although I can fix this issue in many ways (such as using PlotPoints option, changing the plot ranges), this behavior is still surprising to me. Could anyone explain this?

Add the option PlotPoints with a large value:
Plot[f[t], t, 0, 16, Filling -> Axis, Exclusions -> None,
PlotPoints -> 200]
Alternatively,
Quiet @ Plot[f[t], t, 0, 16, Filling -> Axis, Exclusions -> None,
Method -> "MaxBend" -> 0]

f[t_] := UnitStep[t - 14.1] + UnitStep[t - 14.5] + UnitStep[t - 14.9]
Adding Exclusions will cause Plot to look closely in the region of the Exclusions and result in clean steps.
Plot[f[t], t, 0, 16,
Exclusions -> 14.1, 14.5, 14.9,
Filling -> Axis]
EDIT: You will get the same result with Exclusions -> True. END EDIT
Or use the option MaxRecursion
Plot[f[t], t, 0, 16,
MaxRecursion -> 10,
Filling -> Axis]
