Support native PDF LaTeX export

[jgonsior]

Currently I use the inkscape -D -z --file input.svg --export-pdf output.pdf_tex --export-latex to create a PDF file that can be imported into LaTeX and uses the fonts etc. from LaTeX. But I have to manually escape f.e. the percentage signs from the axis or fiddle around quite a lot to make the paddings etc. work. Therefore I'd like to know, if a native latex PDF LaTeX export is on the table for the future.

As a very basic workaround for the font, you can install the Computer Modern font from here and then use it in your Altair code with something like labelFont='CMU Serif'.

AFAIK, matplotlib support exporting plots to latex like:

plt.savefig('figure.pdf', backend='pgf')

I often have to insert plots in latex, and if you could provide similar feature, this will become an advantage of alrair. :)

If that feature is important to you, I’d suggest sticking with matplotlib.

Since Altair 5.2, the functionality of Altair Saver is now available in Altair via the vl-convert package. Most of the functionality has been available since 5.0, and the main addition in 5.2 was PDF export. See the docs on how to save charts for more details.

We are going to archive this repo, so I'm closing all the open issues and PRs before doing so. Try out the new options for saving charts mentioned above and if you run into issues, please open an issue directly in the altair or vl-convert repo.
