I do fit a function from a dataset which I need to display in a LogLogPlot in order to make it display as linear. I do also need to overlay an LogLogErrorBarPlot so they show together in one graphic – which fails. I feel like something is wrong about the LogLogPlot of my fitted model but can’t really tell what it is other that said LogLogPlot looks sketchy (note the y-dimensions…). What I’ve done so far:

Needs["ErrorBarLogPlots`"] ... Cdata = Import[ filepath, {"Data", 1, Range[2, 9], {1, 4, 5, 8, 9}}] Cdata[[All, 1]]  {2000., 3123., 4824., 6989., 9049., 11050., 12950., 14640.} fitList = Transpose[{Cdata[[All, 1]], Zcres[[All, 1]]}]; fitC = NonlinearModelFit[fitList[[All, {1, 2}]],    a/(f), {{a, 2*Pi*107*10^(-9)}}, {f}, Weights -> 1/uZc^2] fitCn = Normal[fitC]; plotList = Transpose[{Cdata[[All, 1]], Zcres[[All, 1]]}] {{2000., 778.53}, {3123., 478.889}, {4824., 297.143}, {6989.,  204.286}, {9049., 152.698}, {11050., 125.135}, {12950.,  106.418}, {14640., 92.7027}} formattedData = Thread[{fitList, ErrorBar /@ uZc}] {{{2000., 778.53}, ErrorBar[0.0000923914]}, {{3123., 478.889},  ErrorBar[0.000156972]}, {{4824., 297.143},  ErrorBar[0.000238414]}, {{6989., 204.286},  ErrorBar[0.000371446]}, {{9049., 152.698},  ErrorBar[0.000485536]}, {{11050., 125.135},  ErrorBar[0.000590405]}, {{12950., 106.418},  ErrorBar[0.00080528]}, {{14640., 92.7027}, ErrorBar[0.0009158]}} errloglogPlot =    ErrorListLogLogPlot[formattedData, PlotStyle -> Red,    PlotRange -> {{1900, 14000}, {0, 700}}] fitloglogPlot = LogLogPlot[fitCn, {f, 1900, 14000}] Show[fitloglogPlot, errloglogPlot,   PlotRange -> {{1900, 1400}, {0, 750}}] 

In the output of “Show[fitloglogPlot, errloglogPlot,…] it just displays my fitloglogPlot… ![output]: (https://imgur.com/a/xBBYu) The upper plot is the errorLogLogPlot which displays just fine, so does a normal Plot of the fit. Bottom ist genereted from “Show…” Id been looking through the documentation but couldn’t find anything.
