X 标签不正确！pgfplots 条形图

我对 pgfplots 还很陌生，我正在尝试使用它来制作条形图，但是 xtick 标签并没有出现在条形图上。

代码：

\documentclass{amsart}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{float}
\usepackage{caption}
\usepackage{pgfplots}
\pgfplotsset{width=12cm,compat=1.13}
\begin{document}
\begin{figure}
\captionsetup{labelformat=empty}
\caption{What Do You Do When You Are Bored?}
\begin{tikzpicture}
  \begin{axis}[
    ybar,
    grid style=dashed,
    axis lines=left,
    enlargelimits=0.5,
    ymin=0,
    ytick={0,.1,.2,.3,.4},
    bar width=1cm,
    xtick={18 \& under,19-64 ,65+,all ages}
    axis lines=left,
    legend style={at={(0.5,-0.2)},
 anchor=north,legend columns=-1},
    ylabel={Popularity},
    symbolic x coords={18 \& under,19-64,65+,all ages},
    xtick={18 \& under,19-64,65+,all ages},
    nodes near coords, 
    nodes near coords align={vertical},
    x tick label style={rotate=45,anchor=east},
    ]
    \addplot coordinates {(18 \& under,.314)};
    \addplot coordinates {(19-64,0.2058333333333)};
    \addplot coordinates {(65+,.18)};
    \addplot coordinates {(all ages,.2255)};
    \legend{Texting, Watching TV, Reading, Talking with friends}
  \end{axis}
\end{tikzpicture}
\end{figure}
\end{document}

得出的结果为：

但是，如您所见，x 标签不在条形图附近。任何帮助都非常感谢。

附注：我该如何减少 x 轴和条形图开头之间的空间量？

答案1

这是我的解决方案，我在选项中添加了和enlarge y limits。前两个命令设置了绘图的 x 和 y 限值，最后一个命令设置了条形之间的空间。我还在绘图内部添加了而不是使用环境并添加。我希望这就是你要找的。enlarge x limitsybar=-1cmaxistitle=...figurecaption
