[Tex/LaTex] Figures stacked rather than side by side when using minipage

minipagesubcaption

I am trying to put a figure, next to four other figures, two up and two down. That is, one figure on the left side, four small figures on the right side (2 by 2)
But whenever I add the subcaption, they end up stacking up instead.

I'd be very grateful if anyone can help me.
Thanks!

\documentclass[]{article}
\usepackage[margin=0.8in]{geometry}
\usepackage{graphicx}
\usepackage{subcaption}    
\begin{document}   
\begin{figure}[ht!]
    \captionsetup{justification=centering}
    \centering
    \begin{minipage}{.49\linewidth}
        \centering
        \includegraphics[width=0.9\linewidth]{figfit22.png}
        \subcaption{Measured spacing as function of pitch}
    \end{minipage}
    \hfill
    \centering
    \begin{minipage}{.49\linewidth}
\centering
\includegraphics[width=0.31\linewidth]{dif42.png}\subcaption{Pitch: 24 $\mu$m}
\includegraphics[width=0.31\linewidth]{dif12.png}\subcaption{Pitch: 83 $\mu$m}
\includegraphics[width=0.31\linewidth]{dif22.png}\subcaption{Pitch: 125 $\mu$m}
\includegraphics[width=0.31\linewidth]{dif32.png}\subcaption{Pitch: 250 $\mu$m}
    \end{minipage}
\end{figure}
\end{document}

Use \subcaptionbox{<caption>}{<image>} instead. Note the warning in the subcaption manual:

Please note that the \subcaption command must be applied inside its own box or environment.

So when using \subcaption, each of them must have its own minipage or similar. With \subcaptionbox you don't need that.

(As I don't have your images I added the demo option to graphicx, you want to remove that.)

\documentclass[]{article}
\usepackage[margin=0.8in]{geometry}
\usepackage[demo]{graphicx}
\usepackage{subcaption}    
\begin{document}   
\begin{figure}[ht!]
    \captionsetup{justification=centering}
    \centering
    \begin{minipage}{.49\linewidth}
        \centering
        \includegraphics[width=0.9\linewidth]{figfit22.png}
        \subcaption{Measured spacing as function of pitch}
    \end{minipage}
    \hfill
    \begin{minipage}{.49\linewidth}
\centering
\subcaptionbox{Pitch: 24 $\mu$m}{\includegraphics[width=0.31\linewidth]{dif42.png}}
\subcaptionbox{Pitch: 83 $\mu$m}{\includegraphics[width=0.31\linewidth]{dif12.png}}

\subcaptionbox{Pitch: 125 $\mu$m}{\includegraphics[width=0.31\linewidth]{dif22.png}}
\subcaptionbox{Pitch: 250 $\mu$m}{\includegraphics[width=0.31\linewidth]{dif32.png}}
    \end{minipage}
\end{figure}

[Tex/LaTex] tables side-by-side using minipage

There are a number of problems here:

The open line between the minipages results in a new paragraph. Comment it out or remove it.
The label command refers to the previous section or chapter and not the table as intended. Put everything inside a table environment and use \caption command to activate the correct labels.
Your tables are too wide for the environments. You can cheat a little bit by putting a wide box inside a zero sized box.

Here is and example:

\begin{table}
\centering
\makebox[0pt][c]{\parbox{1.2\textwidth}{%
    \begin{minipage}[b]{0.32\hsize}\centering
        \begin{tabular}{ | c | c |}
           \hline
           \textbf{Feat. id} & \textbf{F-Measure} \\ \hline
           0 & 0.4286 \\ \hline
           17 & 0.3973 \\ \hline
        \end{tabular}
        \caption{xxx}
        \label{tab:singlebest}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.32\hsize}\centering
        \begin{tabular}{ | c | c |}
           \hline
           \textbf{Feat. id} & \textbf{F-Measure} \\ \hline
           25 & 0.4494 \\ \hline
           11 & 0.4457 \\ \hline
        \end{tabular}
        \caption{xxxx}
        \label{tab:twobest}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.32\hsize}\centering
        \begin{tabular}{ | c | c |}
           \hline
           \textbf{Feat. id} & \textbf{F-Measure} \\ \hline
           18 & 0.4595 \\ \hline
           19 & 0.4565 \\ \hline
        \end{tabular}
        \caption{xxxx}
        \label{tab:threebest}
    \end{minipage}%

[Tex/LaTex] side by side minipage figures

In A) you declare a width of .4\textwidth for the miniboxes and a width of 2in for the images, but 2in > .4\textwidth (with default margins); your images in fact are wider that the space reserved for them and the images overflow over the right margin (check this using the draft class option and looking at the .log file).

In B) the images have now enough space since 2in <.45\textwidth, the minipages fill the text width but not the images; the image in the second minipage is typeset starting the minipage so you will have a white space of width .45\textwidth-2in (you can verify this using \fbox around each minipage setting \fboxsep to 0pt).

In your header you are not taking into account \fboxsep (the spacing between the box and its contents) and this will cause a overfull box (the width for the \parbox must be \textwidth-2\fboxsep).

In the following code I used the draft class option (overfull \hboxes will be signaled using a black rule) and enclosed the minipages using a red frame so you can see what is really going on:

\documentclass[draft]{article}
\usepackage{colortbl}
\usepackage{graphicx}

\newcommand\Mybox[1]{%
  \setlength\fboxsep{0pt}\fcolorbox{red}{white}{#1}
}

\begin{document}

\begin{center} 
\noindent\colorbox{blue}{\parbox[t][0.5cm][c]{\textwidth}{\bfseries{HEADER}}}
\end{center} 

\noindent\begin{minipage}{\textwidth}

%A
\noindent\Mybox{\begin{minipage}[b]{.4\textwidth}
\includegraphics[width=2in]{elephant}
Some text.
\end{minipage}} 
\hfill
\Mybox{\begin{minipage}[b]{.4\textwidth}
\includegraphics[width=2in]{elephant}
Some more text.
\end{minipage}}

\end{minipage}

\vspace{5ex}

%B
\noindent\begin{minipage}{\textwidth}

\noindent\Mybox{\begin{minipage}[b]{.45\textwidth}
\includegraphics[width=2in]{elephant}
Some text.
\end{minipage}} 
\hfill
\Mybox{\begin{minipage}[b]{.45\textwidth}
\includegraphics[width=2in]{elephant}
Some more text.
\end{minipage}}

\end{minipage}

\end{document}

And the result:

enter image description here

Here's a modified version of your code; using width=\linewidth guarantees that the images will take exactly the available space inside the minipages:

\documentclass{article}
\usepackage{colortbl}
\usepackage[demo]{graphicx}
\usepackage{lipsum}

\begin{document}

\begin{center} 
\colorbox{blue}{\parbox[t][0.5cm][c]{\dimexpr\textwidth-2\fboxsep\relax}{\bfseries{HEADER}}}
\end{center} 

\lipsum[2]

\noindent\begin{minipage}[b]{.4\textwidth}
\includegraphics[width=\linewidth]{elephant}
Some text.
\end{minipage}%
\hfill
\begin{minipage}[b]{.4\linewidth}
\includegraphics[width=\textwidth]{elephant}
Some more text.
\end{minipage}

\end{document}
