Hello,

I am creating a fairly complicated groupplot with a shared legend. Since each subplot has its own combination of axis labels, I created options and then I would like to put the into groupplot as an options, like follows

```julia
@pgf gp = GroupPlot({group_style = { group_size = "1 by 1",}, height = "6cm", width = "6cm"});
opts = "title = {title}, ylabel = {y label}, xlabel = {x label} "
push!(gp,opts)

```

which generates following latex code

```julia
\begin{groupplot}[group style={group size={1 by 1}}, height={6cm}, width={6cm}]
    title = {title}, ylabel = {y label}, xlabel = {x label}
\end{groupplot}

```

But I would like the code to be

```julia
\begin{groupplot}[group style={group size={1 by 1}}, height={6cm}, width={6cm}]
   \nextgroupplot[\title = {title}, ylabel = {y label}, xlabel = {x label}]
\end{groupplot}

```

Is there a way, how to achieve this, or I have to put the nextgroupplot by myself, as

```julia
@pgf gp = GroupPlot({group_style = { group_size = "1 by 1",}, height = "6cm", width = "6cm"});
opts = "title = {title}, ylabel = {y label}, xlabel = {x label} "
push!(gp,"\\nextgroupplot["*opts*"]")

```

It is sort of hacky solution, but it works. I am afraid that I am missing the “correct” way to do it.

Thanks for answers.

See [the manual on `GroupPlot`](https://kristofferc.github.io/PGFPlotsX.jl/latest/man/axislike.html#GroupPlot-1), in particular

> `Options` (ie from `@pgf {}`) will emit a `\nextgroupplot` with the given options,

so eg

```julia
julia> @pgf gp = GroupPlot({group_style = { group_size = "1 by 1",}, height = "6cm", width = "6cm"});

julia> opts = @pgf { "title = {title}, ylabel = {y label}, xlabel = {x label}" };

julia> push!(gp,opts);

julia> print_tex(gp)
\begin{groupplot}[group style={group size={1 by 1}}, height={6cm}, width={6cm}]
    \nextgroupplot[title = {title}, ylabel = {y label}, xlabel = {x label}]
\end{groupplot}

```

```julia
opts = @pgf { title = "title", ylabel = "y label", xlabel = "x label" };

```

should also work.

Hi Kristoffer,

thanks for a swift answer. I have read this from the manual, but the trick I need is to generate the options from string as shown above. It is because I construct the options incrementally, for example

```julia
opts = "tile = {title}"
i == 1&& opts*= "..."
mod(i,2) == 1 && opts*=",ylabel = {ylabel}"
i>=5 && opts*=",xlabel = {xlabel}"

```

after which I would like to exec `push!(gp,opts);`

Tomas

You _can_ construct options incrementally, see

Thanks, that has solved the problem.
