# Bar plot with y-error and nodes near coords [closed]

I have to plot some data as a bar plot. These data is processed with pgfplotstable, so I can plot the mean and the error for my data. Now I want to print the nodes near coords for each of the bars; the only thing I get is an error message. See my code with the data below. I use LuaLaTeX to compile.

TL;DR-Version: Code won't compile when nodes near coords and y error used with the same axis.

• This question does not fall within the scope of TeX, LaTeX or related typesetting systems as defined in the help center.
If this question can be reworded to fit the rules in the help center, please edit the question.

• Are all those packages and the calculations of the statistics necessary to reproduce the problem? If they aren't, could you edit your question and boil the code down to the absolute minimum that's required to demonstrate the issue? – Jake May 7 '15 at 16:41
• Most of them are necessary, yes. I'll edit the question and reduce the code. – Ruehrfisch May 7 '15 at 17:19
• This code compiles fine for me, even if I add nodes near coords to the axis options. What error message do you get? – Jake May 7 '15 at 17:25
• That's right. Compiles without error for me, too. I can't reproduce the error now. Maybe there is a problem with my laptop, I compiled it there. Sorry for the problems I caused. – Ruehrfisch May 7 '15 at 19:35
• I'm voting to close this question as off-topic because OP stated that the problem has vanished (by recompiling). – Stefan Pinnow Nov 2 '16 at 13:39
