Graphics, Figures & Tables ⇒ 2*2 subfigure - how to?

[jiapei100]

Hi, all:

I'm trying to arrange 8 figures into 2 subfigures, each of size 2*2.
Namely, I would like to arrange two groups of figures with only 2 captions,
each group has 4 figures. But, to arrange 4 figures in a row will be out of the range. And I've got to arrange 4 figures in the form of 2*2.

So the question could be, how to "change lines" in a subfigure??
Adding "\\" at the end of the 2nd figure doesn't help at all.
My current code for one group of images is like:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
\subfigure[caption 1]{
\mbox{\includegraphics[scale=0.8]{./figures/subfigure1}}
\mbox{\includegraphics[scale=0.8]{./figures/subfigure2}}
\mbox{\includegraphics[scale=0.8]{./figures/subfigure3}}
\mbox{\includegraphics[scale=0.8]{./figures/subfigure4}}
}

Note that I used the demo package option for graphicx to render my example compilable for everyone; do not include that option in your actual code. Of course, use the options for the figures according to your needs.

Another approach could be to use the subcaption package.

Thank you very much for your prompt reply.

1) What is the relationship between these two packages subfigure and subfig?
Are they compatible? I mean, can I use both packages at the same time?
like:

Code: Select all

1

\usepackage{subfigure}
\usepackage{subfig}

2) It looks you created two figures, rather than two subfigures embedded in a single figure.
What I need is something like

Code: Select all

1
2
3
4
5

7

9
10
11
figure

\includegraphics11

Can you please help to just use subfigure package to realize the above required figures?

Thank you ...

Thank you very much for your prompt reply...

You're welcome.

...What is the relationship between these two packages subfigure and subfig?...

subfigure is an obsolete package and it shouldn't be used anymore.

...What I need is something like...

The quickest solution then is to use the subcaption package that I suggested before:

Code: Select all

I guess I could, but I won't; as I explained before, the subfigure package shouldn't be used anymore.

Perhaps I missed something. But didn't you ask similar questions before [1,2]? If the answers have not been satisfying, you could have posted your queries there. Nevertheless these topics are still awaiting your feedback.
