You just need to insert the :transparent symbol into the background_color option. It saves well as *.png, but it is said that it doesn’t save well as *.pdf.

using Plots
plot(rand(10), background_color = :transparent)
png("example")

As you can guess from the option name, if you put in a color symbol, it will be output in that color. For example, a picture drawn with :yellow looks like this.
