Issue with GR plot in Atom

[rveltz]

Hi,

I would like to plot a layout in Atom. But, if there are too many points, nothing is output. For example, changing (in the following example) 20000 to 200000 outputs nothing in Atom with Julia v0.7, osx.

Is it to be expected?

Thank you for your help.

gr()
        Plots.plot(layout=(3,1))
        Plots.plot!(rand(20000),subplot=1)
        Plots.plot!(rand(20000),subplot=2)

I actually currently have this issue in the REPL as well.

I also have this issue. Running Win10 and Julia v1.0. However, savefig() works.

Hi,

Any idea where this might be coming from?

I can even plot Plots.plot!(rand(2000000),subplot=...) - it's probably a question of memory resources in your host environment. Plotting such amounts of data in a reasonable way requires compressing the dataset into much smaller aggregate arrays and display it as an image. This will be supported in the next major GR release.

But it used to work in Atom / julia v0.6.4 ...

[jheinen]

Also 0.6.4 works for me with 2000000 points ...

Plots v"0.17.4"
GR v"0.34.1+"
GR run-time "0.34.1.post6"

Well that shows that the error is in the Plots gr backend, not GR itself.
I wonder if it isn't still the segmentation PR that's increased memory consumption - what do you think @daschw ?

Why? @jheinen used Plots.plot!(rand(2000000),subplot=...) and it worked for him on both, 1.0 and 0.6.4. I don't think we can conclude anything from that.

That was already introduced in Plots 0.17.0 and 0.17.1. Nevertheless, it could still be related. I need to take a closer look, but first I want to finish the docs PRs this weekend.

I see this issue in Atom - Julia v1.0 on OSx.

[28b8d3ca] GR v0.34.1
[91a5bcdd] Plots v0.20.2

not in the REPL.

[daschw]

I also see it in the REPL.

[mkborregaard]

Why?

Because he used GR 0.34.1 on both - am I overlooking something?

[rveltz]

Does anybody could get his hands on the problem in Atom plotting with GR?
