Currently I’m using RCall, to plot in R, but I’m trying to switch to plotting directly in Julia (in Juno IDE, on Linux mint). I’m trying to overlay a plot I made with Plots.jl using the GR backend with a second plot with a differently scaled y-axis on the right side of the picture. The figure I want to produce should look similar to that:
With GR I got as far as the following:
> display(plot(1:Generations, Npop, title=titlemain, lw=2, c= :green,
> xlabel=“Generations”, ylabel=“Populationsize”, ylims=0:(2\*K), leg=false))
This gives me a plot similar to only the green data in the picture.
Now, I want to add a second y axis on the right size and use that to overlay the first (green in the picture) plot with a second line. This is necessary, because the datasets are scaled so differently (up to several 1000 in the first, and 0 - 4 in the second one). Does anybody have an idea how to achieve this? I tried searching the Plots.jl documentation and the GR framework homepage, but I didn’t find info an how to set the side on which the y axis is displayed or how to overlay two plots… I’m really grateful to anybody with an idea!

With Plots, you’d do `plot(vector1); plot(twinx(), vector2)`. You only need to call `display` explicitly if you’re in a context where the plot isn’t returned to console (such as inside a for loop).

Thanks so much! This does exactly what I want! I’m using `display()` because I’m using Juno and without it, the plot isn’t shown in the plotpane. But thanks for the heads up. `twinx()` is exactly what I was looking for and it’s so much easier and faster than using RCall and plotting in R. That’s why I love Julia…

Great to hear 🙂 You might want to ask on the juno gitter channel why your plot isn’t showing, it should…

Thanks! I forgot to include, that I’m using the `plot()` command in a function, so not displaying would be what I would expect, as it’s the same in loops etc. When I’m directly running `plot()` without the envelope, it shows in the plotpane. Thanks for the tip with the gitter channel though 🙂

Quick question just came to mind: How would I go about adding the label to the second (right) y-axis? If I use `ylabel="ylabel"` it appears on the left side, overlapping with the left ylabel… Is there something like `ylabelposition=:right` ? Thanks again!

that’s a bug. Would you mind opening an issue?

Never done that before, but I will try 🙂 Thanks!

I opened an issue for the problem with `twinx()`: [https://github.com/JuliaPlots/Plots.jl/issues/1276](https://github.com/JuliaPlots/Plots.jl/issues/1276)

I am trying to use Plots pyplot() with twinx() but the label on the right side does not appear, neither the vertical line (only the numbers)
