Pgfplots: Replace x-axis numbering with labels on confidence interval plot?

Question

Try as I might, I can't seem to replace the numbering on the x-axis with (arbitrary) labels.

Here is a half-and-half, where the plot has been done in PGPPlots and I've added two of the x-ticks showing how I'd like it to look: I've seen a few examples in relation to barplots, but I can't seem to transfer it to this example. As always, thanks for the consideration.

Update: Got it working with a combination of scale and width. Thanks all.

MWE:

\documentclass{article}
\usepackage{tikz}
\usepackage{rotating}

\usepackage{pgfplots}
\begin{document}
\begin{sidewaysfigure}
\begin{tikzpicture}[scale=1.1],
\centering
\begin{axis}[
height=8cm,
width=15cm,  
  ymax=5,
  ymin=-3,
  xmin=0.5,
  xmax=10.5,
  axis y line*=left,
  axis x line*=bottom]
\addplot+[only marks][error bars/.cd,y dir=both, y explicit]
coordinates {
(10,0.23333) +- (0.58257,-0.1159)
(9,1.4) +- (2.04003,0.75997)

\addplot[dashed] coordinates {(-1,0) (42,0)};

Answer 1

You can use anything as symbolic coordinates: (In fact, the coordinates themselves can be just A,B,C, D etc.) But for your solution, you just need to map the xtick labels. Based on Jakes comment, I've also added xtick={1,...,10} to explicitly map the ticks to the labels.

\documentclass{article}
\usepackage{pgfplots}
\usepackage{rotating}

\begin{document}
\documentclass{article}
\usepackage{tikz}
\usepackage{rotating}
\usepackage{verbatim}
\usepackage{pgfplots}
\begin{document}
\begin{sidewaysfigure}
\begin{tikzpicture}[scale=1.1],
\centering
\begin{axis}[
height=8cm,
width=15cm,  
  ymax=5,
  ymin=-3,
  xmin=0.5,
  xmax=10.5,
  axis y line*=left,
  axis x line*=bottom,
  xticklabels={Duck happy,Cat happy,Octopus happy,Monkey happy, Human happy,Duck sad,Cat sad,Octopus sad,Monkey sad, Human sad},xtick={1,...,10},
  x tick label style={rotate=90,anchor=east}]
\addplot+[only marks][error bars/.cd,y dir=both, y explicit]
coordinates {
(10,0.23333) +- (0.58257,-0.1159)
(9,1.4) +- (2.04003,0.75997)
(8,1.1) +- (1.82293,0.37707)
(7,1.3667) +- (2.0352,0.6981)
(6,0.26667) +- (0.94558,-0.41225)
(5,0) +- (0.59648,-0.59648)
(4,0.9) +- (1.67431,0.12569)
(3,-0.66667) +- (0.09502,-1.42835)
(2,0.56667) +- (1.30495,-0.17162)
(1,0.4) +- (1.06941,-0.26941)
};
\addplot[dashed] coordinates {(0,0) (10.5,0)};
\end{axis}
\end{tikzpicture}%

\end{sidewaysfigure}
\end{document}

Answer 2

This approach comes pretty close. But it is not perfect since the zero x line only connects the first and last x value, thus is not passing the whole plot.

\documentclass{article}
\usepackage{pgfplots}
\usepackage{rotating}

\begin{document}
  \begin{sidewaysfigure}
    \centering
    \begin{tikzpicture}[scale=1.1]
      \begin{axis}[%
        height=8cm,
        width=15cm,  
%        xmin=0.5,
%        xmax=10.5,
        ymax=5,
        ymin=-3,
        axis y line*=left,
        axis x line*=bottom,
                symbolic x coords={A,B,C,D,E,F,G,H,I,J},
        x tick label style={rotate=90,anchor=east},
                xticklabel={Picture~\tick}
      ]
        \addplot+[only marks][error bars/.cd,y dir=both,y explicit] coordinates {%
          (J,0.23333) +- (0.58257,-0.1159)
          (I,1.4) +- (2.04003,0.75997)
          (H,1.1) +- (1.82293,0.37707)
          (G,1.3667) +- (2.0352,0.6981)
          (F,0.26667) +- (0.94558,-0.41225)
          (E,0) +- (0.59648,-0.59648)
          (D,0.9) +- (1.67431,0.12569)
          (C,-0.66667) +- (0.09502,-1.42835)
          (B,0.56667) +- (1.30495,-0.17162)
          (A,0.4) +- (1.06941,-0.26941)
        };
        \addplot[dashed] coordinates {(A,0) (J,0)};
      \end{axis}
    \end{tikzpicture}%
  \end{sidewaysfigure}
\end{document}
