Gaston + DaemonMode: No output window shown

[YggdrasiI]

Hello,

I'm struggling with the combination of Gaston (plotting via gnuplot) and DaemonMode. This minimal example will open a plotting window when called with julia, but does not produce any output/error message within DaemonMode

Did I miss something to setup or is this a Problem of Gaston?

Regards YggdrasiI

using Gaston
#Gaston.set(term="x11")

x = range(0, 2π; length=31)
plot(x, sin.(x))

Dear @YggdrasiI,

Thank you for your interest in my package. Have you tested directly? I have tested, and I have discovered:

• In the REPL, it is working nicely, but you have to uncomment the second line. The reason is that in command line you require it, maybe in a notebook is not needed.
• Running it with julia ... it does not work, because the program quit before the visualization can be shown. There is not any pause. Thus, try to save the figure to check it.

By the way, I recommend you julia plots: https://docs.juliaplots.org/latest/ or Makie (https://docs.makie.org/stable/), in conjunction with https://aog.makie.org/stable/. In my opinion, they are better options.

Good evening dmolina,

thanks, you've pointed me in the right direction. I made a mistake and it also not open the plotting window if the script is running with julia {scriptname} on my computer(s).

So it turns out it was the rookie mistake caused by Julia's plotting technique.
For completeness and other beginners, like me: Outside of the REPL the drawing of a figure needs an explicit display(...) call. Otherwise the output will be omited. A working example will be following code. This will also work in DaemonMode as expected.
In my case the setting of terminal doen't matter. It will also draw with the default value (qt).

using Gaston
Gaston.set(term="x11")

x = range(0, 2π; length=31)
fig = plot(x, sin.(x))
display(fig)

Your suggestion to use Makie is generally correct. In my case, however, I come from there and had problems using GLMakie on all computers and was looking for a variant that runs everywhere without code changes.
