I hope following helps,

Putting plots with different domain together:
a) you can do this by drawing two Plot's with DisplayFunction->Identity and
after that using them in Show[{plt1,plt2}] with
DisplayFunction->$DisplayFunction invoked.
b) The same thing is already done for you if you load <<Graphics`Graphics`
Add-On and use built-in DisplayTogether, which works self-explanatory.


In[22]:=
sol1 = NDSolve[{y'[t] == -1/100 y[t], y[0] == 1}, y, {t, 0, 200}][[1]]

Out[22]=
{y -> InterpolatingFunction[{{0., 200.}}, "<>"]}

In[30]:=
sol2 = NDSolve[{y'[t] == -1/100 y[t], y[200] == Exp[-2]},
      y, {t, 200, 1000}][[1]]

Out[30]=
{y -> InterpolatingFunction[{{200., 1000.}}, "<>"]}

In[7]:=
<< Graphics`Graphics`

In[33]:=
DisplayTogether[
  {
    LogPlot[Evaluate[y[t] /. sol1], {t, 0, 200}, PlotStyle -> Hue[0]],
    LogPlot[Evaluate[y[t] /. sol2], {t, 200, 1000}, PlotStyle -> Hue[.55]]
    }
  , PlotRange -> All
  , Frame -> True
  , Axes -> False
  ]
