Which is fine, apart from how the x-axis ticks are displayed.
What can that be due to? Maybe too large values? The values in the x-axis should be in the range 10^5 or 10^6.

Do you have any suggestions in order to visualize the x-axis ticks correctly?

What do you expect to see? Is your question about the error in rendering the exponents on the x-axis? Or do you think you should have different values on the x-axis?

It’s hard to help here, it’d be great if you could provide a full MWE as described here and explain what you’re hoping to see on your plot.

@nilshg thank you for your reply, and you are right, I should have included more details, please refer to the following.
My question was about the error in rendering the exponents on the x-axis. I would expect to see integers, or e.g. 10^4, 2*10^4, etc.; but not a square instead of the exponents.

The structure of the code is the following:

using Plots
pyplot()
wanted_font = "garamond"
fig_1 = plot(
tickfont = wanted_font, legendfont = wanted_font, guidefont = font(9, wanted_font),
xlabel = "My x-axis", ylabel = "My y-axis",
legend = false, grid = false,
xmin = 0, ymin = 0
)
while # a certain complicated condition ...
plot!(fig_1,
[scalar_1], [scalar_2],
c = [1],
marker = (:circle, 1),
markerstrokewidth = 0.1
)
end
savefig(fig_1,"name.jld")

By the way, I’m using Julia 0.6.4.
Thank you in advance!

The exponents are rendered using Unicode superscript, and I’m not sure if Garamond supports those. Maybe try a font which does? I think Noto should (for one).
