条形图-‘内部’x 刻度？

Question

我今天成功创建了我的第一个“条形图”：

通过使用下面给出的代码：

\documentclass[tikz,border=1pt]{standalone} 
\usepackage[ngerman]{babel}                         
\usepackage[ansinew]{inputenc}  
\usepackage[T1]{fontenc}                            
\usepackage{graphicx} 
\usepackage{pgfplots}
\usepackage{amsmath} 
\usepackage{units}
\usetikzlibrary{matrix}

\pgfplotsset{compat=1.10, 
        saeule-style/.style={
          title={\textbf{Bar Chart}},
        },
        height=6cm,
        width=20cm,
        grid=major,
        grid style={
          solid,
          ultra thin,
          gray
        },
        xmin=1925,
        xmax=1975,
        xtick={1925,1930,...,1975},
        x tick label style={
            rotate=90
        },
        x tick style={
          color=black,
          thin
        },
        ymin=0,
        ymax=10,
        y tick style={
          color=black,
          thin
        },
        xlabel={\textbf{Year}},
      ylabel={\textbf{Population}},
      legend columns=2,     
        legend style={
            font=\scriptsize,
            legend pos=north west,
            draw=none,
            /tikz/column 2/.style={
        column sep=10pt,
      }
        },
      ybar=5pt,
      nodes near coords,
      /pgf/number format/.cd,
      use comma,
      set thousands separator={},
} 


\begin{document}     

 \begin{tikzpicture} 
    \begin{axis}[saeule-style]
        \addplot[ybar, bar width=0.2cm, fill=blue, draw=black] coordinates {(1930,5) (1940,3) (1950,4) (1960,5) (1970,7)};
            \addplot[ybar, bar width=0.2cm, fill=red, draw=black] coordinates {(1930,3) (1940,4)    (1950,4) (1960,4) (1970,6)};

            \legend{Far,Near}
    \end{axis} 
 \end{tikzpicture} 

\end{document} 

如您所见，我添加了 x 和 y 轴。正如我所料，y 轴被绘制出来了在图表。不幸的是，xtics 没有。似乎有什么东西给了它们一种“外部”选项。

你们中有人知道我该如何放置它们吗？在图表？

提前谢谢你，eniem

编辑：嗯...现在尝试使用“xtick align=inside”选项，但它不起作用。有人知道为什么吗？

引用手册ybar；

它改变图例，在轴线外绘制刻度，并绘制彼此相邻的多个 \addplot 参数；......

所以这是意料之中的事。不过，您可以通过一些小的调整来覆盖这一点，xtick align=inside正如@Jake 在评论中提醒的那样，它会自动为您完成。

\documentclass[border=1pt]{standalone} 
\usepackage{pgfplots}
\pgfplotsset{compat=1.10, 
        xtick={1925,1930,...,1975},
        x tick label style={rotate=90,xshift=-4mm},
        ybar=5pt,
        xtick style={/pgfplots/major tick length=-2mm,draw=black,thick}
} 


\begin{document}     

 \begin{tikzpicture} 
    \begin{axis}
        \addplot[ybar, bar width=0.2cm, fill=blue, draw=black] coordinates {(1930,5) (1940,3) (1950,4) (1960,5) (1970,7)};
            \addplot[ybar, bar width=0.2cm, fill=red, draw=black] coordinates {(1930,3) (1940,4)    (1950,4) (1960,4) (1970,6)};
    \end{axis} 
 \end{tikzpicture}
