plot font problems

[jonathon]

hi laurent,

can you send me a .omv file containing this plot?

with thanks

I can confirm the same font issue on Debian 10 with Gnome 3.
I use flatpak installed from backports (1.6.2-1~bpo10+1).
Jamovi console output:

Code: Select all

flatpak run org.jamovi.jamovi

No font-related messages.

Also it is impossible to export graph as pdf, png, svg, e.t.c.
I have a feeling, that it has the same system-related-library-issue root.
What font is used for graphs?

And no results with

Code: Select all

flatpak run --command=fc-cache org.jamovi.jamovi -f -v

Tried to reproduce this problem in virtual machines with Ubuntu 20.04 and Arch Linux (minimal install with LXDE). But everything worked fine, I saw fonts.
But on Debian Testing I was able to reproduce the same font issue.

I`ve attached screenshots and omv.

cool, thanks for these details. can you just check that this still occurs with the latest jamovi (1.2.18). we ship the 1.2.18 with a newer R version, and i just want to rule out that that makes a difference.

Problem still exists in 1.2.18 version. I think it is freetype/fontconfig configuration or dependency issue. May be I can experiment with it, but what font is used for plots?

[jonathon]

i'm not really sure what font is used for plots, it's just left at defaults. Q, did this used to work?

can you try rolling back to 1.2.16 and see if that fixes it. rolling back versions of flatpaks is a bit ugly, but there's instructions here:

https://github.com/flatpak/flatpak/issues/3097

i'd normally figure out the commands for you myself, but my linux VM is on an external HD at the moment, and it takes over an hour to bring it online. let me know if you get stuck, and i'll boot it, but if you can figure it out yourself it will save me some time

with thanks

I tried 1.2.16 and 1.2.14 and got the same result - no letters, only senseless symbols on plots.

Another iteration of my fonts journey. Fedora 31 - jamovi works as expected. I can see letters on my plots.
So, as result, Arch Linux, Ubuntu 20.04, Fedora 31 - jamovi shows letters on plots, but it is impossible to export plots as pdf, svg, e.t.c. (Evaluation error: unrecognized format).
Debian (Buster, Testing) - symbols instead letters on plots and the same export problem.

Added later:
OK, I tried to experiment with locales

Code: Select all

flatpak config --system --set languages "en;ru"
flatpak update
flatpak run --env=LC_ALL=en_US.UTF-8 org.jamovi.jamovi

and permissions using Flatseal (granted all possible).
No results.

Added a bit later:
But I`ve successfully reproduced code in R and got plots with words.

Code: Select all

library("jmv")
jmv::pca(
  data = data,
  vars = vars(A, B, C, D, E),
  screePlot = TRUE)

I really think now it is flatpak platform issue, locale or something else.

[jonathon]

thanks for this. i don't suppose any of these are occuring in a VM you could make available to us?

with thanks

[jonathon]

the exporting of plots i can reproduce, and will take a look at ... that looks to be a bug in electron (you'll notice that at the bottom right, you can choose the format; pdf, svg, etc.) the filename *should* be provided to us with the extension on it, but electron doesn't seem to be doing this correctly.

you can add the file extension manually to get it to work in the mean time.

cheers

[jonathon]

*blergh*, the extension issue is a "won't fix" in electron

https://github.com/electron/electron/issues/21935

i've no idea how we can work around it.
