Underscore in treatment names not escaped

[MatthiasJakobs]

If there are underscores in the treatment names, they are not escaped correctly so that compilation does not work.

File for reproduction:

\begin{tikzpicture}[
  treatment line/.style={rounded corners=1.5pt, line cap=round, shorten >=1pt},
  treatment label/.style={font=\small},
  group line/.style={ultra thick},
]

\begin{axis}[
  clip=false,
  axis x line=center,
  axis y line=none,
  axis line style={line cap=round},
  xmin=1,
  xmax=6,
  ymin=-4.5,
  ymax=0,
  scale only axis,
  height=5\baselineskip,
  width=\axisdefaultwidth,
  ticklabel style={anchor=south, yshift=1.3*\pgfkeysvalueof{/pgfplots/major tick length}, font=\small},
  every tick/.style={draw=black},
  major tick style={yshift=.5*\pgfkeysvalueof{/pgfplots/major tick length}},
  minor tick style={yshift=.5*\pgfkeysvalueof{/pgfplots/minor tick length}},
  axis line style={-},
  title style={yshift=\baselineskip},
  xtick={1,2,3,4,5,6},

Thanks for reporting!

pip install --upgrade 'critdd @ git+https://github.com/mirkobunse/critdd'

This issue is resolved by the latest commit 8c062a6, to which the package is upgraded through the command above. Let me know if any problem remains.

By the way, if you stumble across underscore problems elsewhere (EDIT: or, if you do not want to re-produce the LaTeX source of your plot), you can use the underscore LaTeX package:

\usepackage{underscore}
