unbound-slot error when invoking `eplot`

[Luis-Henriquez-Perez]

After doing as you say instead of producing a display I get the following error after invoking eplot.

These are what I use. GNU Emacs 29.3 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.41, cairo version 1.18.0) Arch Linux x86_64

Then say `M-x eplot' in this buffer, and you'll get this displayed:

I tried reproducing the problem, but was unable to. Is this with a brand-new checkout of eplot?

[Luis-Henriquez-Perez]

Maybe its due to the fact that I installed it via elpaca. How did you install it, manually?

(elpaca (eplot :host github :branch "main" :repo "larsmagne/eplot"))

Elpaca bc685f5 HEAD -> master, origin/master, origin/HEAD
installer:      0.7
emacs-version:  GNU Emacs 29.3 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.41, cairo version 1.18.0)
git --version:  git version 2.45.2

Also I need to update elpaca. When Im able I'll update it and tr to install it again.

Oh and to answer your question this is the commit of eplot I'm using:

5751000 * main origin/main grafted More build requirements

Hm... that looks OK, but it doesn't really say whether it's up-to-date or not.

(I don't use a package manager for eplot.)

[Luis-Henriquez-Perez]

I assumed it installed it at the latest commit and unusuallyy it didnt so upgraded eplot to the latest commit. But I upgraded it, rebuilt it, restarted my emacs and tried invoking eplot again:

dcc82f7 * main origin/main Add installation instructions to README But I got the same backtrace:

I'll give it a shot manually. And Im curious if this also happens with package-vc-install so I might try it there too.

I assumed it installed it at the latest commit and unusuallyy it didnt so upgraded eplot to the latest commit. But I upgraded it, rebuilt it, restarted my emacs and tried invoking eplot again:

dcc82f7 * main origin/main Add installation instructions to README But I got the same backtrace:

Debugger entered--Lisp error: (unbound-slot eplot-chart "#" print-format oref)

Ah, I'm able to reproduce the problem now -- it just needed to be in an emptier buffer. I'll get fixin'.

[larsmagne]

This should now be fixed.

After upgrading, rebuilding and invoking M-x eplot I get a new backtrace. This is at the latest commit: Head: main Don't bug out when called in an empty buffer

I think I've fixed this one, too...

The base problem here is that it can't parse the buffer you're running M-x eplot in -- what does it look like?

Oh I didn't know u had to run it in a specific buffer. I called it in a buffer with elisp code. I thought it would use a default data set if no data was provided (not that I am saying this should be the behavior I am speaking litterally with no double meanings). Now that I know that I tried it in one of the sample data sets you provided. Got to say pretty cool!

[larsmagne]

Thanks! And since it now gives a better error message, I'm closing this issue, then.
