Gadfly: adding line-styles to the plot legend

General Usage
1

Dear community,

I want to create a plot with several lines that have different line-styles (e.g., solid, dashed, dotted,…), and to add these styles to the legend of the plot (to fit for a black-white publication). Is there any built-in option for that in the meanwhile, or a better work around than this one?

Thank you in advance and kind regards,
Michael

Hi, I found that PyPlot is actually better for this purpose, here’s my code:


    subplots()
    xlabel("x",fontsize=14)
    title("Title",fontsize=14)
    yscale("log")
    grid("on")
    ylabel("Time (s)",fontsize=14)
    plot(X,time1,label="Label1",color="orange",linewidth=3)
    plot(X,time2,label="Label2",color="green",linestyle="--",linewidth=3)
    plot(X,time3,label="Label3",color="blue",linestyle="-.",linewidth=3)
    legend()
    xticks(X)
    ax=gca()
    ax.set_xlim([X[1],X[end]])
    ax.legend(loc="upper left")

Hope it helps.

I haven’t used Gadfly, but with Plots you can do this:

using Plots
plot(rand(10, 5),
     line = [:solid :dash :dot :dashdot :dashdotdot],
     color = :black)

For Gadfly, there’s examples of the linestyle aesthetic here.
In the tutorial, Guide.linekey is marked as to be done.

Thank you all. I gave a try using Plots together with PyPlot as backend, and this seems to work fine for my purposes.
