I am including horizontal and vertical error bars in a ListLogLogPlot, and for some reason it seems like the horizontal endcaps attached to the vertical error bars only show up sporadically throughout the plot, and not on every point. Can someone help me figure out what’s going on?

Hi j bg,

Looks like a bug, you should report it to [Wolfram Support](https://www.wolfram.com/support/contact/email/?topic=feedback). It seems to be caused by the small y values. Here is a workaround.

Scale the y values by 10^13

```
measScaled = MapAt[#*10^13 &, meas, {All, 2}];

```

Plot with scaled frame ticks

```
mwePlot = ListLogLogPlot[measScaled,
  GridLines -> Automatic,
  GridLinesStyle -> Black,
  FrameStyle -> Black,
  Frame -> True,
  FrameLabel -> {"PAS Detuning [GHz]", 
    "\!\(\*SubscriptBox[\(K\), \(\[Nu]\)]\)/I \
[\!\(\*SuperscriptBox[\(cm\), \(5\)]\)\!\(\*SuperscriptBox[\(mW\), \
\(-1\)]\)\!\(\*SuperscriptBox[\(s\), \(-1\)]\)]", "", ""},
  BaseStyle -> {FontSize -> 14},
  PlotLegends -> \
{"\!\(\*SuperscriptBox[\(\[InvisiblePrefixScriptBase]\), \(86\)]\)Sr, \
exp. "},
  PlotRange -> {{3, 500}, {10^-3, 10^2}},
  PlotStyle -> {GrayLevel[0.5], PointSize[Large]},
  ImageSize -> Large,
  FrameTicks -> {{Charting`ScaledTicks[{Log[# 10^13] &, Exp[#]/10^13 &}], Automatic}, 
      {Automatic, Automatic}}]

```
