Figure numbers in Lyx and PDF are differnt!

Question

I am using Lyx 2.1 and Adobe Acrobat Reader DC for thesis. I need to figures to be numbered for each chapter, i.e. Fig 2.3 for second chapter's third figure. I tried the codes recommended in the forum but it didn't work out. So I returned to flat numbering. Now the problem is the number in Lyx is 1,2,3, ... but in pdf it resets in start of each section ie. first figure of each section is 1.1 and second 1.2 and in the start of next section again 1.1? Can anybody help me with this. (The class is NUThesis and I don't have any module and preamble). The class file is here, LyX Layout for the NU Thesis Class. The code that I used: \makeatletter \@addtoreset{figure}{chapter}% Reset figure numbering at every chapter \makeatother \renewcommand{\thefigure}{\arabic{chapter}.\arabic{figure}}% Figure number is chapter.figure

Answer 1

With the following code :

\documentclass[print]{nuthesis} % Require http://www.math.unl.edu/graduate/nuthesis/nuthesis.zip
\begin{document}
    \chapter{Foreword}
    \section{First section}
    \begin{figure}
        \caption{First figure}
    \end{figure}
    \section{Second Section}
    \begin{figure}
        \caption{Second figure}
    \end{figure}
     \begin{figure}
            \caption{Third figure}
        \end{figure}
    \chapter{Introduction}
    \section{A second first section}
    \begin{figure}
        \caption{Forth figure}
    \end{figure}
    \section{A second second section}
    \begin{figure}
        \caption{Fifth figure}
    \end{figure}
\end{document}

I get figures numbered 1.1, 1.2, 1.3, 2.1, 2.2.

Isn't that the behavior you expect?
