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?

    $\begingroup$ This works on OSX 10.9.4 when you add Joined -> True. Without it I see the same behaviour you are experiencing. $\endgroup$

  • $\begingroup$ 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] $\endgroup$

  • $\begingroup$ Thanks, Matariki. That brings the error bars back for me as well, but makes the plot exceptionally ugly. Hopefully there is another fix somewhere. $\endgroup$

  • $\begingroup$ 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. $\endgroup$

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.

    $\begingroup$ It's still there in 10.0.1, alas. $\endgroup$

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

Fixed in 10.0.2. windows 7, 64 bit

Mathematica graphics

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]

Mathematica graphics

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

  • $\begingroup$ With Joined -> False the error bars disappear again. This is not entirely fixed therefore. $\endgroup$

    $\begingroup$ 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. $\endgroup$

    $\begingroup$ Same for me, no error bars in 11.2.0, not even using the Method -> {"OptimizePlotMarkers" -> False} trick... $\endgroup$
