How to remove the little bars on the axis while keep the labels at the same time?

Question

When I do this:

\begin{figure}[h]
\centering
\footnotesize
\pgfplotsset{
   width=0.45\textwidth,  
   height=0.3\textheight,
   symbolic x coords={2007,2008,2009,2010,2011,2012,2013,2014,2015,2016,2017,2018},  
   %enlarge y limits={upper,value=0.05},  
   }
\begin{tikzpicture}

\begin{axis}[
   xtick=\empty,
   xticklabels={2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018},
    ybar,                         
   bar width=0.2cm,               
   ymin=0, ymax=1200,
   ytick={0, 200, 400, 600, 800, 1000, 1200},
   ylabel style={align=center},
   ylabel={Number of publication containing the keywords \\ ``ciprofloxacin + resistance''},
   xticklabel style={
      inner sep=0pt,
      anchor=north east,
      rotate=60
      },
   ]
    \addplot[thick,fill=baishu,draw=baishu] plot coordinates{
     (2007,888) (2008,908) (2009,920) (2010,1010) (2011,1003) (2012,1081) (2013,1082) (2014,1075) (2015,1092) (2016,1100) (2017,1049) (2018,789)  %%%resist
      };
   \end{axis}

\end{tikzpicture}

\label{resist}
\end{figure}

there is no x labels.

When I do this:

\begin{figure}[h]

   %enlarge y limits={upper,value=0.05},  %Y轴顶端的距离
   }
\begin{tikzpicture}

\begin{axis}[

      },

    \addplot[thick,fill=baishu,draw=baishu] plot coordinates{

      };
   \end{axis}

\end{tikzpicture}

\label{resist}
\end{figure}

the little bars above can't be removed...

besides, how to put those x axis little bars inner side?

Answer 1

Here is one possibility: use xtick align=inside, after ybar.

\documentclass{article}
\usepackage[margin=1in]{geometry}
\usepackage{pgfplots}
\begin{document}
\pgfplotsset{compat=1.16,axis on top,
   width=0.45\textwidth,  
   height=0.3\textheight,
   symbolic x coords={2007,2008,2009,2010,2011,2012,2013,2014,2015,2016,2017,2018},  %X___
   %enlarge y limits={upper,value=0.05}, 
   }
\begin{tikzpicture}
\begin{axis}[tick pos=left,
   xtick={2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018},
   xticklabels={2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018},
   ybar,     
   xtick align=inside,                    
   bar width=0.2cm,               
   ymin=0, ymax=1200,
   ytick={0, 200, 400, 600, 800, 1000, 1200},

   ylabel={Number of publication containing the keywords \\ ``ciprofloxacin + resistance''},
   xticklabel style={

      },
   ]
    \addplot[thick,fill=blue,draw=blue] plot coordinates{
