You must take the Log of the vertical axis range values


data = RandomVariate[
   TruncatedDistribution[{-2, 2},
    NormalDistribution[0, 0.5]], 1000];


Histogram[data, 10, {"Log", "PDF"},
 PlotRange -> {{-2, 2}, Automatic},
 Frame -> True,
 PlotRangeClipping -> True]


Histogram[data, 10, {"Log", "PDF"},
 PlotRange -> {{-2, 2}, Log /@ {0.01, 1.0}},
 Frame -> True,
 PlotRangeClipping -> True]


However, since Log is Listable, this can be shortened slightly to


Attributes[Log]


{Listable, NumericFunction, Protected}


Histogram[data, 10, {"Log", "PDF"},
 PlotRange -> {{-2, 2}, Log at {0.01, 1.0}},
 Frame -> True,
 PlotRangeClipping -> True]
