Graphics, Figures & Tables ⇒ Legend inside caption

[jhapk]

Hi,

I have a figure like this

figure.png (51.1 KiB) Viewed 9417 times

Instead of having the legend in the figure, I want to have it in the caption, like

Code: Select all

[draw red line] FPI- Method 1, [draw green line] FPI- Method 2

Is it possible?

The easiest way would probably be just to use a dash (or two for a dashed line).

Code: Select all

\caption{blablabla. {\red -}: $\mu=1$, {\green -}: $\mu=2$, {\blue -}: $\mu=3$, {\red --}: $\mu=4$, {\green --}: $\mu=5$ \dots

Or: Use pspicture (or some other package) to actually draw a line.
Or2: save the line separately and use it in line with \includefigure[height=1em]{Images/line}

I too wish there was an easier way to do this...

I think that shifting the legend to the caption is not so good. There are other possibilities for tweaks which might look better.

You could decrease the font size of the legend to reduce its size so it doesn't cover so much of the plot area. Moreover you can place the legend somewhere else inside as well as outside the plot area. Both methods are described in the pgfplots manual.

Finally a tip that is not problem related. Perhaps you should think about placing the y-axis label a bit further to the left. It interferes with tick labels. The manual shows you how to do that.

Thanks localghost. Your suggestion made sense. I used the "legend pos" command explained in pgfplots and I could position my legend easily.

You can use tikz package with protect, as suggested in

https://tex.stackexchange.com/questions/115352/tikzpicture-within-figure-caption

Code: Select all

\documentclass{article}
\usepackage{tikz}
\begin{document}

\begin{figure}[h]
-- This is a figure --
\caption{Figure within caption {\protect\tikz \protect\draw[thick, color=blue, fill=blue] plot[mark=*, mark options={scale=1.3}] (0,0);} }
\end{figure}

\end{document}
