res[x_] := 
 2.8464*10^-11 x /{((x/34.5) - 
   10^-14) ((1 - (60/x)^2)^0.5 /(64 Pi x^2) + 
   2 (1 + 0.5 (1 - 
         2 (x/80.4)^2))*80.4^4 (1 - (80.4/
           x)^2)^0.5/(8 Pi x^2 ((4 x^2 - 60^2)^2 + 60^2 125^2)) + 
   2 (1 + 0.5 (1 - 
         2 (x/91)^2))*91^4 (1 - (91/
           x)^2)^0.5/(16 Pi x^2 ((4 x^2 - 60^2)^2 + 
         60^2 125^2)) + 
   992.255 (1 - (120/x)^2)^(3/2) /((4 x^2 - 60^2)^2 + 
       60^2 125^2))}

This is my function and it should be plotted in the range

LogLogPlot[res[x], {x, 10^0, 10^3}, 
PlotRange -> {{10^0, 10^3}, {10^-5, 10^2}}]

But i am getting a Partial part of my required graphenter image description here But should be like enter image description here

  • $\begingroup$ Your function has an imaginary component in a range of values for x. $\endgroup$ – b.gates.you.know.what May 15 at 21:11

    $\begingroup$ I think you should recheck your function... for starters there is a List in there for some reason, for seconders, it doesn't seem to return real numbers for the whole range you are plotting. $\endgroup$ – chuy May 15 at 21:12
