Specify Label Locations
A callout can be given a specific location and anchor point with both x and y coordinates.
In[1]:=
LogPlot[{Callout[x^(Log[x] Sin[x]), x^(Log[x] Sin[x]), {3, 3}, 2.5],
x^(Log[x] Cos[x]), x^(Log[x/2] Sin[2 x])}, {x, 1, 6},

Labeled can be given an x coordinate and a relative position.
In[2]:=
Plot[{WeberE[1, x], WeberE[2, x],
Labeled[WeberE[3, x], WeberE[3, x], {2.5, Above}]}, {x, -5, 5},
