How to arrange 8 figures, with subcaptions, in a 3-row form

Question

I want to figure out how to make an arrangement of eight figures into a compact form as shown in the picture. Could some give a hand?

you could use subfloats as explained here: https://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions#Subfloats — naphaneal, Jul 03 '16 at 12:23

Which LaTeX document class do you use? Not all subfigure-related packages are compatible with all document classes? — Mico, Jul 03 '16 at 12:44
I refer to ' How can I arrange multiple figures in rows of 3 in a two-column document? , still I found a problem. in that example, all the subfigure started with fig x:, in my case, i wished it to be (a)(b)..., i was wondering how to change that, thanks — user4756766, Jul 03 '16 at 13:47

Thanks for mentioning in a comment which document class you use -- IEEEtran, with the option conference. Since this document class uses a two-column layout, the first and most important measure to take is to employ a figure* environment, which takes up the width of both columns, instead of a "normal" figure environment.

To position the eight subfigures along with their \captions within the figure* environment, I suggest you load the subcaption package and use that package's subfigure environment. In the following code, the amount of whitespace between the graphs in the third row is set to be same as it is in the first two rows, viz., 0.05\textwidth. If you want more horizontal separation between the graphis in the final row, simply increase the value of the argument of next-to-last \hspace* directive.

\documentclass[conference,demo]{IEEEtran}  % remove 'demo' option in real document
\usepackage{graphicx,subcaption}
\begin{document}

\begin{figure*}
% first row: 3 subfigures
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{fa}
   \caption{xxx} \label{fig:x_a}
\end{subfigure}
\hspace*{\fill}
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{fb}
   \caption{xxx} \label{fig:x_b}
\end{subfigure}
\hspace*{\fill}
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{fc}
   \caption{xxx} \label{fig:x_c}
\end{subfigure}

% 2nd row: 3 more subfigures
\bigskip
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{fd}
   \caption{xxx} \label{fig:x_d}
\end{subfigure}
\hspace*{\fill}
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{fe}
   \caption{xxx} \label{fig:x_e}
\end{subfigure}
\hspace*{\fill}
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{ff}
   \caption{xxx} \label{fig:x_f}
\end{subfigure}

% 3rd row: just 2 subfigures, centered
\bigskip
\hspace*{\fill}
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{fg}
   \caption{xxx} \label{fig:x_g}
\end{subfigure}%
\hspace*{0.05\textwidth}%
\begin{subfigure}{0.3\textwidth}
   \includegraphics[width=\linewidth]{fh}
   \caption{xxx} \label{fig:x_h}
\end{subfigure}
\hspace*{\fill}

\caption{yyy}
\end{figure*}
