Bar from bar chart without value

Question

I would like to add a single bar to my chart, but without any value. Unfortunately when I skip adding proper value with label x in coordinates, it (bar with label x) disappears from chart.

\begin{tikzpicture}
\begin{axis}[
   width=\textwidth,
   ybar,
   enlargelimits=0.10,
   legend style={at={(0.5,-0.2)},
   anchor=north,legend columns=-1},
   symbolic x coords={A,B,C},
   xtick=data,
   nodes near coords,
   nodes near coords align={vertical},
   x tick label style={rotate=45,anchor=east},
   ]
  \addplot coordinates {(B,5) (C,7)};
\end{axis}
\end{tikzpicture}

In this example bar A (and label A) will not appear on the chart. Anybody knows how to put this x label to chart?

Answer 1

Here is a suggestion using

   symbolic x coords={A,B,C},
   xtick={A,B,C},
   xmin=A,
   ymin=0,
   enlarge y limits={0.1,upper},

Code:

\documentclass[margin=5mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
   width=\textwidth,
   ybar,
   enlargelimits=0.10,
   legend style={at={(0.5,-0.2)},
   anchor=north,legend columns=-1},
   symbolic x coords={A,B,C},
   xtick={A,B,C},
   xmin=A,
   ymin=0,
   enlarge y limits={0.1,upper},
   nodes near coords,
   nodes near coords align={vertical},
   x tick label style={rotate=45,anchor=east},
   ]
  \addplot coordinates {(B,5) (C,7)};
\end{axis}
\end{tikzpicture}
\end{document} 

Answer 2

Another one with testing value of the bar value and deciding to put the node near coord or not. In case you need it for some obscure reason. The test should have been easier but somehow ifthenelse is not overloaded in this context. The output is the same as above

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.10}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
   width=\textwidth,
   ybar,ymin=0,enlarge y limits=false,
   enlarge x limits=0.10,
   legend style={at={(0.5,-0.2)},
   anchor=north,legend columns=-1},
   symbolic x coords={A,B,C},
   xtick=data,
   nodes near coords*={%
     \pgfmathprintnumberto[fixed,assume math mode]{\pgfplotspointmeta}{\temp}%
     \ifnum\temp=0\else\pgfmathprintnumber{\pgfplotspointmeta}\fi%
   },
   nodes near coords align={vertical},
   x tick label style={rotate=45,anchor=east},
   ]
  \addplot coordinates {(A,0) (B,5) (C,7)};
\end{axis}
\end{tikzpicture}
\end{document}
