My students and I have been developing a package in Julia, and under the test directory, we have a file runtests.jl as the other packages. In it, we try to run some plotting functions to show some graphics (via Plots.jl), but when I run this via ] test MyPackage, say, the test passes without any err…

[image] BVPs: we try to run some plotting functions to show some graphics (via Plots.jl ), but when I run this via ] test MyPackage , say, the test passes without any errors, but it does not generate any graphical plots. Hard to say more without a minimal working example. [image…

Try capturing the output and then calling display: julia> p = plot(rand(5)); # no graphical output produced julia> typeof(p) Plots.Plot{Plots.GRBackend} julia> display(p) When you don’t use the semicolon, the show/display method is called implicitly, which is why you expect to see graphical o…

Hi, Tim. Thanks for your advice. I have tried both methods you mentioned. However, the image still can’t be displayed. The best I can get is one line of "Plot{Plots.GRBackend() n=1} " showing that one image variable was created.

Probably far too late, but I recently encountered the same problem when using the package PyPlot.jl when executing the tests in tests\runtests.jl of my project. What worked for me was to call ion() before the first plot command. After creating the plot, I used pause(5) to allow some time for inspe…

@Nikos_Gianniotis ; thanks a lot for your suggestion. But have you tried these ion and ioff under Plots.jl’s pyplot() backend? I am not using PyPlot.jl directly. I always use Plots.jl with various backends.

Hi @BVPs . I’m afraid I only ever use PyPlot.jl and have no experience with other plotting packages. I understand that Plot.jl can use PyPlot.jl as a backend, but I have never even installed it. One hears good things about Plots.jl though…sorry!

In this situation I would probably have it save the images as png or pdf.
