This shouldn't happen, I'll have a look asap.

Did you try pythonplot ? It's a drop in replacement for pyplot.

[shayandavoodii]

Did you try pythonplot?

Is it a package?

[t-bltg]

pkg> add PythonPlot
julia> using Plots
julia> pythonplot()

See also the announcement at https://discourse.julialang.org/t/ann-plots-1-37-rfc-plots-2-0/91270.
And also the docs.

Thanks. It worked.

[t-bltg]

Glad it worked. In the mean time, the pyplot bug will be fixed by #4592.

I will merge and tag a new Plots release asap.
Sorry for the inconvenience.

Thanks a lot! There isn't anything to be sorry about! Well done.

I broke it, I fix it ;)
