Is there a way to save a figure with transparent background color in Plots.jl? pyplot can do that by transparent=True.

Yes: background_color = :transparent. You might also need to set your foreground_color to :black, because otherwise the axes and grid lines seem to come out white for some reason.

@sswatson Thank you for the help. It seems to work for .png but not for .pdf. I tried the following code and got nice png and black background pdf. using Plots p=plot([1,2,3], background_color=:transparent, foreground_color=:black) savefig(p, "test.png") # work nicely savefig(p, "test.pdf") # not…

Looks like a GR issue. Both PDF and PNG work for me with the PyPlot backend.

@sswatson Oh, that is right. Thank you!!

Works in plain GR: julia> using GR julia> plot([1,2,3]) julia> savefig("test.png") julia> savefig("test.pdf") Both files are transparent. So, it’s a problem in the Plots gr backend code.

Yes—I should have said an issue with the GR backend, not necessarily GR per se. Presumably what’s happening is that the color :transparent—which is an RGBA black with an alpha value of zero—is being passed to GR in such a way that the alpha value gets lost. I suppose this means that Plots.jl isn’t …

Is there a way to save a plot with transparent background to a pdf file?

Have you tried pgfplotsx() backend?

nope. I didn’t know this backend… Is this backend new? I am on julia 1.6.1, and I don’t see it there. Should I upgrade?
