I need number of figure by chapter:

I'm using this but sometimes it repeats the numeration

usepackage{chngcntr}

counterwithin{figure}{chapter}

counterwithin{table}{chapter}

example:

chapter1

  figure 1.1

  figure 1.2

  figure 1.3

chapter2

  figure 2.1

 section 2.1

  figure 2.2

  figure 2.3

chapter3

  figure 3.1

  figure 3.2

 section 3.1

  figure 3.3

example:

     documentclass{report}

usepackage{float}

usepackage{chngcntr}

counterwithin{figure}{section}



begin{document}

chapter{}

section{section 1.1}



begin{figure}[H]

centering

rule{1cm}{1cm}% placeholder for graphic

caption{A figure}

end{figure}



begin{figure}[H]

centering

rule{1cm}{1cm}% placeholder for graphic

caption{A figure}

end{figure}



section{section 1.2}



begin{figure}[H]

centering

rule{1cm}{1cm}% placeholder for graphic

caption{A figure}

end{figure}







chapter{}

section{section 2.1}



begin{figure}[H]

centering

rule{1cm}{1cm}% placeholder for graphic

caption{A figure}

end{figure}



end{document}

this is the screeshot:

• Use report class when chapters are needed.


• Remove some packages (not needed to get the output).


• 
  

  Do not include numbers in section and chapters (those are created automatically by latex)

  
  
  

  documentclass{report}
  
  
  
  usepackage{float}
  
  
  
  begin{document}
  
  
  
  chapter{ } %if you want a name write it as chapter{name}
  
  
  
  
  
  
  
  begin{figure}[H]
  
  centering
  
      rule{1cm}{1cm}% placeholder for graphic
  
  caption{A figure}
  
  end{figure}
  
  
  
  section{}
  
  
  
  begin{figure}[H]
  
  centering
  
  rule{1cm}{1cm}% placeholder for graphic
  
   caption{A figure}
  
  end{figure}
  
  
  
  section{ }
  
  
  
  begin{figure}[H]
  
  centering
  
  rule{1cm}{1cm}% placeholder for graphic
  
  caption{A figure}
  
  end{figure}
  
  
  
   end{document}
