add export table data to file

[jguterl]

This is a proposition to permit export of table data to file and shorten tikz files.

Usage:
p=plot()
x = collect(0:0.001:1.0)
y = @. 1-sqrt(1-x^2)
plot!(y,x,ylabel="Δq/qᵤ", xlabel="q_rad/qᵤ")
path = "/yourpath/here/"
Plots.PGFPlotsX.export2tikz(path * "delta_q.tex",p;relpath="figures")

[jguterl]

That can be generalized to the various types of plots very easily.

Can you please explain the use case? Yes, the tikz file would be shorter, but the same data ends up in another file, so what is the net gain?

Discussed a bit in #223.

[jguterl]

Two purposes: 1) avoiding 10000 lines file (e.g. multiple subplots with multiple data easily reach that mark. yes that can reduced by curating data but that defies the purpose of an efficient plotting routine) that makes any manual edit to the axis and tikzpicture very painful 2) allow to add/update data to the tikz figure without updating the tikz file itself (e.g want to add a curve on a subplot or f= in the data)

I don't really like this whole new export2tikz function. I think it should be possible to implement this as an argument to pgfsave.

The steps I am thinking are:

• Each data source that can use an external file (for example Table) needs a modification to print_tex that allows it to save the data to a file.
• When a file is saved to .tex with the external_data=true keyword argument:
  -- We set a global flag that we are currently saving with external data (and to what folder it is being saved)
  -- The data sources look at that global flag and instead of just printing the tex output, it also creates the data file.
  -- The naming of the data files is $(filename)_data_$(n).tsv where $n is a global counter.
  -- Before saving the file, all previous files of that name pattern above are removed (need to be a bit careful here, should probably add a header or something to do file which is checked so we don't remove user files).

That way, the only change a user has to do when exporting with separate data files is to add the ; external_data=true keyword to pgfsave.

I agree with the general idea. The way it is working now is the following : - a temp file is created for each table data. - those temp files are moved (could be copied) once the export2tikz is called toward the chosen path Could we use external_data with savefig directly? This is the most practical feature for beginners.

alternatively, is it possible to make a dispatch for pgfsave that accommodates plot types from Plots.jl e.g.: using Plots() pgfplotsx() p=plot() pgfsave("filename.tikz",p) On Fri, Apr 14, 2023 at 12:00 PM Jerome Guterl ***@***.***> wrote:

Not really, but Plots allows you to get the underlying object which could be passed to pgfsave for example. Or savefig (or whatever Plots uses to save plots) could pass keywords down to the backend (maybe it already does).

[jguterl]

so far, it seems to me that savefig is only a wrapper for MIME writing methods. That's why I ended up with a export2tikz function that is actually using the same MIME writing method as Plots.jl.
