LyX ⇒ Subfigure without number [solved]

[roby92ita]

Hi, I'm new in the forum. I'm writing my thesis using LyX, v. 2.2.2, and I've got a problem with subfigures.
I'd like to recall the label in the description of the Figure like (a) and (b), but using the cross reference I have 1(a) and 1(b); instead in the text I want exactly 1(a) and 1(b). Like:


(a) graph1 (b) graph2
Figure 1: (a) graph1 and explanation, (b) graph2 and explanation

In fig. 1(a) there's the graph1 about...

I've tried using \subref command, and it works but with an error: "Argument of \caption@ydblarg has an extra }." that I don't understand.
There's some method to overcome this problem? I've searched trough the forum but without result.
I hope I explained myself well.

Hi Roby,

welcome to the forum!

Do you use the subfigure package, or subfig? I recommend the latter, since that one is newer.
Maybe take a look at the (here linked) package manual how that works.

Package subcaption is even better with respect to hyperlink support.

Thanks everyone,
the package subcaption is in conflict with the package subfigure that is automatically used by LyX and I don't know how to remove it.
With the package subfig I have the exact problem that i described, maybe it is because I use the insert Image and Insert Label of Lyx instead of using the ERT to load the image?

Can you post a minimal example where you get the conflict in LyX? If so I can take a look.

[roby92ita]

I made a little file showing what I want to do, hope it help understanding the problem.
The conflict appear when I put in the Preamble \usepackage{caption}, so if you put that in the Preamble of my file I think you'll get the same problem.
Thanks

I know how to disable loading the subfig package in LyX, but then \subfloat is not defined. What do you ideally want the LaTeX output to look like? Perhaps you could post what LyX creates as LaTeX and what you wish it would be. Then I can see if it is possible to have LyX do it.

Thanks, LyX generate:

Take a look at the attached .lyx file. I think it gets close to what you want. A few things to note:

1. In Document > Settings > Local Layout, I put "Provides subfig 1". This basically tells LyX "don't worry about automatically loading this, I will do it myself"
2. In the LaTeX Preamble, we load the package.
3. There is some ERT required for e.g. "\subref{cat}", which is not very elegant. This will be improved a bit in LyX version 2.3 (still not close to being released), where you can enter a label directly. With that improvement, we could make a custom inset for "\subref" and no ERT would be required.

It's perfect like this, thanks a lot!
