Hello,
I need to put on the same graph three lines with different y-axis). I know how to do it with two y-axises (one is right and the other is left).
How to do it with 3 lines, so the left y-axis has to be double.
thank you in advance.
Best

I think the best advice I can give is “don’t”, two axes is already slightly less than one too many.
That said, have you considered
```julia
plot(...)
twinx(...)
twinx(...; ymirror=true)
```
?

thank you,
But here, 2dn and 3rd y-axises overlapped, unfortunately, it’s not doubled

Okay, there is probably no simpler alternative than using insets with manual bboxes for that. And the reason is most people would consider that poor visualization. Compared to
```julia
plot(
plot(...),
plot(...),
plot(...);
layout=(3,1)
)
```
the triple-axis plot is just harder to read.
But if you’re using it internally where you can learn to read it once and will then use the same layout many times I guess there is no issue with it if you get it to work.

Have you tried using [PyPlot.jl](https://github.com/JuliaPy/PyPlot.jl) to implement [Multiple Yaxis With Spines](https://matplotlib.org/stable/gallery/ticks_and_spines/multiple_yaxis_with_spines.html) ?

In Makie you can use the `ytickalign` keyword for the Axis to move the position of the yticks.
```julia
using GLMakie
a = sin.(1:0.01:6); b = sin.(1:0.01:6) .+ randn.();
c = cos.(1:0.01:6) .+ 20
fig = Figure(resolution=(1200,700))
ax1 = fig[1,1] = Axis(fig, ytickalign=-5, yticklabelcolor=:blue)
ax2 = fig[1,1] = Axis(fig, yaxisposition=:right)
ax3 = fig[1,1] = Axis(fig, ytickalign=0, yticklabelcolor=:red)
plot!(ax1, a, color=:blue)
plot!(ax2, b)
plot!(ax3, c, color=:red)
hidexdecorations!(ax1)
hidexdecorations!(ax2)
linkxaxes!(ax1,ax2)
linkxaxes!(ax1,ax3)
```
This would produce this plot

I have the same problem but unfortunately GLMakie did not work for me. The data in addition to the Jupyter Notebook file can be found here: [https://datashare.mpcdf.mpg.de/s/uPOltmpkDjlZl4F](https://datashare.mpcdf.mpg.de/s/uPOltmpkDjlZl4F)
I am doing the following:
```julia
using Plots
using CSV
using DataFrames
using Colors
df_1 = DataFrame(CSV.File("Energy.csv"))
df_2 = DataFrame(CSV.File("Population.csv"))
df_3 = DataFrame(CSV.File("Ppm.csv"))
a=18
plot(df_2.Year,df_2[:,4],
xlims=(1800,2021),
label = "Population",
ylabel = "World Population",
color=RGB(0.337, 0.631, 0.749),
linewidth=3,
legend = :topleft,
grid = :off,
size = (1600,800),
left_margin = 10Plots.mm,
right_margin = 50Plots.mm,
xtickfontsize=a,
ytickfontsize=a,
xguidefontsize=a,
yguidefontsize=a,
legendfontsize=a)
p = twinx()
plot(p,df_3.Year,df_3[:,4],
xlims=(1800,2021),
label = "Global CO₂ atmospheric concentration",
ylabel = "Global CO₂ concentration in ppm",
color =RGB(0.439, 0.368, 0.470),
linewidth=3,
legend = :topright,
grid = :off,
size = (1600, 800),
left_margin = 10Plots.mm,
right_margin = 50Plots.mm,
xtickfontsize=a,
ytickfontsize=a,
xguidefontsize=a,
yguidefontsize=a,
legendfontsize=a)
p = twinx()
plot!(p,df_1.Year,df_1.sum,
xlims=(1800,2021),
label = "Energy Consumption",
ylabel = "World Primary Energy Consumption",
color =RGB(0.949, 0.352, 0.219),
linewidth=3,
legend = :left,
grid = :off,
size = (1600, 800),
left_margin = 10Plots.mm,
right_margin = 50Plots.mm,
xtickfontsize=a,
ytickfontsize=a,
xguidefontsize=a,
yguidefontsize=a,
legendfontsize=a)
```
The result is the following:
What I would like to change:
- Move the Y-ticks + Y-label of ‘Energy’ to the right
- Color the Y-ticks + Y-label of each graph
- Put all legends to the :topleft in decending size order.
Please help me to make the plot pretty again

I came up with a satisfying solution myself, after finally finding a solution to move the y-axis label here [In Plots.jl, how does one control the space between ylabel and yaxis? - #15 by Andre\_Mello](https://discourse.julialang.org/t/in-plots-jl-how-does-one-control-the-space-between-ylabel-and-yaxis/5717/15).
