[BUG] Plots too large with GR backend in Pluto after Plots 1.8 update

[lungben]

Details

After the Plots.jl update to V1.8, plots with the GR backend are very large by default in Pluto.jl, see attached screenshot and example notebook.

With Plots V1.7, the plot size for GR backend was fine. With the Plotly backends, the size is fine both for Plots.jl V1.7 and V1.8.

We (SolidStateDetectors.jl) also have this issue when compiling our Docs via Documenter.jl

[fhagemann]

Same problem appears when plotting with GR in jupyter notebooks.
The problem does not occur when plotting with pyplot though.

[nicolamos]

Same problem here with Jupiter notebooks. The plots are fine in the GKS Term.
I created a fresh environment and added only Plots and IJulia to test this.

[daschw]

I'm really sorry for this. The issue seems to occur with GR version 0.53. The Pluto notebook in the issue description works, if you add

Pkg.add(PackageSpec(name="GR", version="0.52"))

to the first cell.

@jheinen do you know what change in GR 0.53 might cause this and how we can fix it in Plots?

[jheinen]

Hmm. Strange - don't see any problem in plain GR. Will check it later ...

[jheinen]

To be honest: I don't understand this section. The result is much too big, so I don't see a problem within GR. Did the values vor px or pt probably change in Plots.jl?

Simplifying the expression seems to fix the problem:

gr_point_mult(s) = get_thickness_scaling(s) / 500  # divide by nominal window height

[jheinen]

Same with @myrddin89 problem. Works fine in plain GR:

[jheinen]

@daschw : IMO some scaling parameters in Plots.jl have changed, which have not been adapted in the GR backend code.

[jheinen]

Also, the PNG output is OK:

[daschw]

But why does it work with Plots 1.8 and GR 0.52, but not with Plots 1.8 and GR 0.53? I'm not aware of any recent scaling Parameter changes for GR in Plots. I could not find any in the diff of Plots 1.8.0 vs 1.7.4.

[jheinen]

... in my opinion the problem occurred well before Plots 1.7.4

May be we have to different bugs: the text height and the window size. Right now, I'm totally confused ...

Would be easier for me, if any of the problems would occur in plain GR.

[jheinen]

@daschw : Which GR run-time are you using with Plots 1.8 and GR 0.53? (Plots.GR.version())
