I don't know what you mean by "holes" in graphs. Asymptotes (and other
embellishments) can be handled through the use of graphics primitives and
the function Epilog. This essentially superimposes on a plot another
(usually) simpler plot, like a straight line, which can be instructed to
appear dashed or in a different color, etc. This topic requires some study
and experimentation before you can feel comfortable with it. But it pays. I
give you a simple example:
In[1]:=
Plot[1 - Exp[-x], {x, 0, 5}, AxesOrigin -> {0, 0},
PlotRange -> {{0, 5}, {0, 1}},
Epilog -> {Hue[1], Dashing[{0.01, 0.02}], Line[{{0, 1}, {10, 1}}]}];
Evaluate this to see a red, dashed asymptote.
