As far as I know, those warnings indicate that you have previously loaded another plotting package, for example with using Plots. If Gaston is the only loaded plotting package, those warnings should not appear.

Get this alert when trying to run the example. Gnuplot.jl works correctly

Would you mind opening an issue? Please let me know your OS, gnuplot version, and julia version. I can’t reproduce the problem in my own Linux installation.

If you’re on Windows, please run set(term="qt") before plotting. It seems that some versions of gnuplot have trouble with the default windows terminal (see https://github.com/mbaz/Gaston.jl/issues/161).

I’m glad it worked. I’m going to release a new version that fixes this problem in Windows as soon as I have a bit of free itme.
