Notate the original value form (not logged) in loglog plot

General Usage

The x value vector x=[5e-10, 5e-9, 5e-8, 5e-7, 5e-6]. If plot(,xticks=x) then it’s marked after logged. Can I notate it by 5e** scale correspondingly? Also, is it possible to tick y=collect(0:10:100) by its original form on y axis not logged?

You can do something like this in Gaston, which uses gnuplot to plot:

using Gaston
t=1:0.01:10
set(axis="loglog")
plot(t,sin.(2π*t).+2,gpcom="set xtics 0, 2, 10 nologscale")

which produces

The key part is the nologscale tics parameter. See page 190 in Gnuplot’s 5.2 user manual for more details.

I searched for the error report but only found

Sorry I got confused. Is Gaston availale to Julia1.3.0 or this system? Also, if this can be solved, can the same syntax be applied in scatter()?

Yeah – you need to install gnuplot too: gnuplot download

And yeah – the same syntax is available to scatter.

The flexibility is awesome!

I installed Gaston from

Though a warning appears after installation

But in julia, using Gaston is successful. However, it keeps reporting
config not defined

julia> using Gaston

julia> t=1:0.01:10
1.0:0.01:10.0

julia> Gaston.set(axis="loglog")

Hmh, that’s a new one… Is this in a fresh Julia session? Are you running Gaston v0.10 (not master)?

BTW, you can run set(...) and plot(...), without Gaston. at the start.

thanks but that’s the reason I added Gaston. before set

julia> using Gaston
julia> t=1:0.01:10
julia> set(axis="loglog")
ERROR: UndefVarError: config not defined
julia> plot(t,sin.(2π*t).+2,gpcom="set xtics 0, 2, 10 nologscale")
ERROR: Unknown key: gpcom

Yes it’s

julia> Pkg.API.installed()["Gaston"]
v"0.10.0"

The only reason I can think of for getting this message is that you’re running the same session where using Gaston failed (because gnuplot was not installed), and something was left uninitialized. Can you try exiting Julia and starting again?
