[Tex/LaTex] subfloat vertical alignment

subfloats

I am having a problem aligning figures in a subfloat. Here is the raw code:

\begin{figure}
\centering 
\subfloat[]{{\includegraphics[width=.48\textwidth]{image1.pdf} }\label{}}%
\newline
\subfloat[]{{\includegraphics[width=.48\textwidth]{image2.pdf} }\label{}}%
\newline
\subfloat[]{{\includegraphics[width=.98\textwidth]{image3.pdf} }\label{}}%
\caption{}
\label{}
\end{figure}

I would expect the labels (a), (b) and (c) to be on the centreline of the page. The code gives no errors, but images 1 and 2 are not in the centerline of the page (i.e. their labels (a) and (b) are offset to the left).

I have read this might be something to do with using the width command but I am not sure how to fix it.

Thanks

better than use \\ instead of the \newline, is to insert blank line:

\documentclass{article}
\usepackage[demo]{graphicx} % in real document remove option"demo"
\usepackage{subfig}

\begin{document}
    \begin{figure}
\centering
\subfloat[]{{\includegraphics[width=.48\textwidth]{image1.pdf} }\label{fig:mycaption-a}}

\subfloat[]{{\includegraphics[width=.48\textwidth]{image2.pdf} }\label{fig:mycaption-a}}

\subfloat[]{{\includegraphics[width=.98\textwidth]{image3.pdf} }\label{fig:mycaption-c}}
\caption{My caption}
\label{fit:mycaption}
    \end{figure}
\end{document}

[Tex/LaTex] Subfloat caption width requirements and alignment problems

Here are some suggestions to fix your current situation:

Note the subfloat notation:
```
\subfloat[<LoF>][<subcaption>]{<body>}
```
Since your <body> consisted only of a \label command, the <subcaption> (actually, the <LoF> entry) had to wrap around something that is "very thin", causing it to not typeset properly. See page 4 of the subfig documentation for an explanation of this.
Also, the \label should be included in the <body>.
If you put the entire \subfloat within a fixed-width environment, the caption will wrap according to that width. This can be achieved via a minipage environment, for example. In the following minimal example, I've defined two new commands:
```
\vertfig[<subcaption>]{<body>}% For vertical figure placement
\horizfig[<subcaption>]{<body>}% For horizontal figure placement
```
that you can use to replace the traditional \subfloat. \vertfig typesets its contents in a 5in-width minipage, while \horizfig does so in a 3in-width minipage. Both dropped the second optional argument of \subfloat[..][..]{...}, since it didn't seem to matter to you.

As you can see, no fixed-width \captionsetup is required, since the captions wrap to the box they're contained in.

Different subfloats with different widths

\documentclass[11pt]{article}
\usepackage[a3paper]{geometry}% http://ctan.org/pkg/geometry
\usepackage{graphicx}% http://ctan.org/pkg/graphicx
%\usepackage{caption}% http://ctan.org/pkg/caption
\usepackage{subfig}% http://ctan.org/pkg/subfig
\newsubfloat{figure}
\pagestyle{empty}% No header/footer
\newcommand{\vertfig}[2][]{%
  \begin{minipage}{5in}\subfloat[#1]{#2}\end{minipage}}
\newcommand{\horizfig}[2][]{%
  \begin{minipage}{3in}\subfloat[#1]{#2}\end{minipage}}
\begin{document}

\begin{figure}[ht]
  \centering
  \vertfig% \subfloat
    [This is probably the biggest tiger you will ever see in your life.
     The caption associated with this subfloat should span more than one
     line even though the width of the contents is 5in.]
    {\includegraphics[width=5in]{tiger}\label{fig:vizcardfront}}

  \vertfig% \subfloat
    [Data submission form on the back of the view guide.]
    {\includegraphics[width=5in]{tiger}\label{fig:vizcardback}}
  \caption{The visibility monitoring view guide.}\label{fig:viewcard}
\end{figure}

\begin{figure}[ht]
  \centering
  \horizfig%\subfloat
    [Here is another picture of the tiger, this time a little smaller.
     It is still very fierce-looking, right?]
    {\includegraphics[width=3in]{tiger}\label{fig:plantcam}}
  \hfill
  \horizfig%\subfloat
    [A HOBO$\textsuperscript{\textregistered}$ data logger for air and soil data.]
    {\includegraphics[width=3in]{tiger}\label{fig:logger}}
  \caption{Automatic data collection instruments.}\label{fig:autodata}
\end{figure}

\end{document}

geometry was merely used to set the paper size to a3paper.

[Tex/LaTex] centering figure, containing a \subfigure with customized \includegraphics

Try putting the subfigure inside a minipage, see below,

\begin{figure}
\centering
\begin{minipage}{0.5\textwidth}
\subfigure[comment]{\includegraphicsJustified{images/img1.png} }
\subfigure[comment]{\includegraphicsJustified{images/img2.png} }
\end{minipage}
\caption{whole comment}
\end{figure}

I firmly believe that you can carry out the rest of the fine tuning.

Hope this helps.
