Bug introduced in 10.0.0, fixed in 10.1

I recently upgraded to Mathematica 10, very excited about the multiple undo function of course.

However I very quickly noticed that if I specify a setting for PlotMarkers in the ErrorListPlot function, the error bars disappear. Even just setting PlotMarkers->Automatic makes the error bars disappear. This was not a problem in Mathematica 9, but appears to be a new 'feature'. Has anyone else noticed this since upgrading, and are there any possible fixes?

    This works on OSX 10.9.4 when you add Joined -> True. Without it I see the same behaviour you are experiencing. – Matariki Jul 29 '14 at 09:30
  • Reproduced in my V10 under Win 7, 64 bit by using this code: Needs["ErrorBarPlots`"]; ErrorListPlot[ Table[{i, RandomReal[0.5]}, {i, 10}], PlotMarkers -> Automatic] – Tetsuo Ichii Jul 29 '14 at 09:32
  • Thanks, Matariki. That brings the error bars back for me as well, but makes the plot exceptionally ugly. Hopefully there is another fix somewhere. – nate Jul 29 '14 at 09:51
  • I'm still seeing this exact error in 10.0.2 on Mac OS X (10.10.2 Yosemite). The Method -> {"OptimizePlotMarkers" -> False} workaround doesn't seem to have any effect at all. – ibeatty Feb 24 '15 at 18:59
  • @Ian I converted your answer to a comment. If you wish to address this further please post a new question. – Mr.Wizard Feb 24 '15 at 19:50
  • Can anyone confirm that this is not fixed in 10.0.2 under OSX? – Mr.Wizard Feb 24 '15 at 19:50
  • @Mr.Wizard For me (v10.0.2 OSX10.9.5) : when the only option set is PlotMarkers -> Automatic the error bars disappear. If I add the option Method -> {"OptimizePlotMarkers" -> False} OR if I add Joined->True the error bars come back. Do you get error bars on WindowsOS when Joined->False ? – SquareOne Feb 24 '15 at 20:22
  • @SquareOne Good catch. With Joined->False the error bars disappear again. I am removing the "fixed in ..." header. – Mr.Wizard Feb 24 '15 at 22:01
  • NB: the workaround Method -> {"OptimizePlotMarkers" -> False} has to go before the PlotMarkers option for this to work (for me, anyway). – evanb Mar 05 '15 at 01:28
  • For me the bug is there in "11.3.0 for Linux x86 (64-bit) (March 7, 2018)". If I specify any option for PlotMarkers the error bars disappear. The work around also does not help. – Kvothe Apr 04 '19 at 13:42

I heard from technical support. The problem should be fixed in an upcoming release, but for now there is a temporary fix by inserting Method -> {"OptimizePlotMarkers" -> False} into the ErrorListPlot options.

Even just setting PlotMarkers->Automatic makes the error bars disappear

Fixed in 10.0.2. windows 7, 64 bit

Needs["ErrorBarPlots`"]
ErrorListPlot[{{{1, 1}, ErrorBar[0.2]}, {{2, 2}, ErrorBar[0.1]}, {{3, 4}, 
   ErrorBar[0.3]}, {{4, 6}, ErrorBar[0.4]}, {{5, 7}, 
   ErrorBar[0.8]}, {{6, 10}, ErrorBar[0.5]}}, Joined -> True]

ErrorListPlot[{{{1, 1}, ErrorBar[0.2]}, {{2, 2}, ErrorBar[0.1]}, {{3, 4}, 
   ErrorBar[0.3]}, {{4, 6}, ErrorBar[0.4]}, {{5, 7}, 
   ErrorBar[0.8]}, {{6, 10}, ErrorBar[0.5]}}, Joined -> True, 
   PlotMarkers -> Automatic]

Update

To answer comment below

With Joined -> False the error bars disappear again.

This last part has now been fixed in 10.1 (windows). The bars remain when Joined->False is added

  • With Joined -> False the error bars disappear again. This is not entirely fixed therefore. – Mr.Wizard Feb 24 '15 at 22:02

    @Mr.Wizard fyi, the Joined->False is now fixed in 10.1, updated – Nasser Apr 02 '15 at 11:23

    Has there been a regression in 11.2.0? I run your last line (ErrorListPlot[{{{1, 1}, ErrorBar[0.2]}, {{2, 2}, ErrorBar[0.1]}, {{3, 4}, ErrorBar[0.3]}, {{4, 6}, ErrorBar[0.4]}, {{5, 7}, ErrorBar[0.8]}, {{6, 10}, ErrorBar[0.5]}}, Joined -> False, PlotMarkers -> Automatic]) and I get no error bars. I am running 11.2.0 on linux. – Brian Moths Dec 13 '17 at 02:41

    Same for me, no error bars in 11.2.0, not even using the Method -> {"OptimizePlotMarkers" -> False} trick... – mjayvizzle Feb 24 '18 at 00:32
