[Tex/LaTex] Align subfigures centrally in LyX

floatslyxsubfloats

In LyX, I am placing 2 figures side-by-side by placing 2 subfloats inside a single float. This allows me to have individual captions for each subfloat and hence, each sub-figure. My problem is that the 2 figures are different sizes and are not aligned vertically. One figure is taller (longer) than the other and, as they are both aligned to the bottom of the float, the resulting output file doesn't look quite right.

I would like to align the side-by-side figures along their centerlines. Is it possible to do this, so as some whitespace will exist above and below both figures? Alternatively, is it possible to simply move the smaller figure upwards in a vertical direction from the bottom so that it lies somewhat centrally, relative to the other figure? I would prefer one of these options as opposed to messing about with resizing figures.

I have tried using various formatting tools such as Vertical Spaces to move the smaller figure upwards but none of these seem to be working. Any assistance on this matter would be appreciated as I have done numerous searches but the only available solutions I could find was to use minipages and vertical spaces. However, using minipages looses the captions in the sub-figures.

This is straight-forward in LaTeX. The idea would be to save the larger image in a box. Once this is done, you can measure it's height and move the smaller image up by some distance relative to the larger one.

In terms of LyX you can follow these instructions:

Insert the following in your Document > Settings... > LaTeX Preamble:
```
\newsavebox{\savedimage}
\newcommand{\saveimageheight}[2][]{%
  \savebox{\savedimage}{\includegraphics[#1]{#2}}}
\newcommand{\raiseimage}[2][]{%
  \raisebox{.5\dimexpr\ht\savedimage-\height}{%
    \includegraphics[#1]{#2}}}%
```
The above creates two macros: \saveimageheight[<options>]{<image>} that you should use to store the larger of the two images. Use [<options>] that you would normally specify with the original larger image.
Place \saveimageheight[<options>]{<image>} in your document before the smaller of the two images.
Use \raiseimage[<options>]{<image>} to place the smaller image.

This is what the code would look like in LyX:

[Tex/LaTex] margin caption and subfloat

You can use the floatrow package instead of mcaption:

\documentclass{scrartcl}
\usepackage{subcaption}
\usepackage{floatrow}

\captionsetup[capbesidefigure]{format=plain,justification=RaggedRight,
font=small,labelsep=newline}

\begin{document}

{
\floatsetup[figure]{margins=hangleft,capposition=beside,
capbesideposition={top,right},floatwidth=\textwidth,capbesidewidth=1.5\marginparwidth}
\begin{figure}
  \begin{subfigure}[b]{.5\linewidth}
    \centering\large A
    \caption{A subfigure}\label{fig:1a}
  \end{subfigure}%
  \begin{subfigure}[b]{.5\linewidth}
    \centering\large B
    \caption{Another subfigure}\label{fig:1b}
  \end{subfigure}
  \caption{A test figure}\label{fig:1}
\end{figure}
}

\ref{fig:1b}

\end{document}

enter image description here

To obtain captions in the outer margin, you can use the options facing=yes, and capbesideposition={top,outside}:

\floatsetup[figure]{facing=yes,margins=hangoutside,capposition=beside,
capbesideposition={top,outside},floatwidth=\textwidth,capbesidewidth=1.5\marginparwidth}
\captionsetup[capbesidefigure]{format=plain,justification=RaggedRight,
font=small,labelsep=newline}

[Tex/LaTex] Ruled Algorithms in columns/minipages

Benoit Guillon's Algorithm-Style Package for LyX was written in the year 2001. It makes the LaTeX package algorithmic available to LyX in an interesting form. For writing algorithms, the potential of nested lists is used. (Because at that time LyX modules were not available there is the requirement of using a certain document class. But this could be revised...)

Now, how to print two algorithms side-by-side in a LaTeX document is shown in Diego’s CS research blog. This can be transformed into "pure" LyX almost completely.

For each algorithm-float do
- set its "Placement Options" (e.g., by right click) to "Here definitely" to stop it floating -- this is important otherwise an error occurs,
- enclose the float by a minipage whose width is a fraction of the column width (e.g., 45% of column width);
Remove all white spaces (including new lines) between the minipages and "Insert > Formatting > Horizontal Space..." "Horizontal Fill";
Add TeX code/ERT \begin{figure*} before the first minipage and \end{figure*} after the last minipage to make the block of algorithms floating again.

Here is a picture of a LyX document followed by the PDF output.
