[Tex/LaTex] How to control figure numbering in Lyx

floatslyxnumbering

I have a single figure in a Lyx document, and it is part of a paragraph which itself is part of a section. It is expected that Lyx will produce a caption for it as 'Figure 1: ….', however, the actual output I get is 'Figure 0.1: …'. I don't think I explicitly ask Lyx to number the figures by section.

Any clue on why this happens and how I can fix it? In addition, is it possible to eliminate the numbering of captions (not the captions themselves) all together? Many thanks.

P.S. The document class I am using is 'handout (Tufte)' and the paragraph (which itself is of standard text) containing the figure is after two itemized paragraphs, if those make any difference.

Some classes number figures and tables and perhaps further objects by chapter or by section. Let's say in your case it's section. Besides printing the section number before the figure number, the figure counter is reset to zero at the beginning of each section. The chngcntr package helps to change this. Here for example:

\usepackage{chngcntr}
\counterwithout{figure}{section}

Just put these lines in your LyX document preamble. You can add further such lines if necessary, to be consistent, such as

\counterwithout{table}{section}

if you use tables.

For suppressing numbering and further customization I recommend using the caption package. For example:

\usepackage[figurewithin=none]{caption}

Its command \caption* works without numbering.

In my master document I have (in TeXnicCenter):

\appendix
\input{Appendix1}
\newpage
\input{Appendix2}

etc. And in my Appendix documents (I am using article class):

\section{Name of the Appendix}
\label{sec:Appendix1}

And then it appears as Appendix A, Appendix B, etc. in the document and in the TOC.

Use the chemstyle package with option floatrow (to make sure the floatrow package will be used by the chemstyle package) and put a \RawFloats as first command inside the figure:

\documentclass[twoside,a4paper]{report}
\usepackage[demo]{graphicx} % option "demo" added for compiling without images
\usepackage[floatrow]{chemstyle}
\usepackage{enumitem}

\begin{document}

\begin{figure}[ht]
\RawFloats
    \begin{minipage}[b]{0.48\linewidth}
        \begin{itemize} [ ] % To get list without points
            \item{Blah blah blah
                \begin{enumerate}
                    \item{Text}
                    \item{Text}
                \end{enumerate}
            }
            \item{More blah blah blah
                \begin{enumerate}
                    \item{Text}
                    \item{Text}
                \end{enumerate}
            }
        \end{itemize}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.48\linewidth}
        \centering
        \includegraphics[scale=0.2]{caption_example.pdf}
        \caption{default}
        \label{fig:label}
    \end{minipage}
\end{figure}

\end{document}

(The \RawFloats command is described in the floatrow package documentation.)
