Using Plots.jl with pgfplots() backend

New to Julia
,

I am using MacOS. I have been a long-time PyPlot user and I want to switch to Plots.jl

My setup is using vim and julia REPL in a terminal side-by-side.

I have the following set of very basic questions:

  1. When I use pgfplots, it opens inkscape within XQuartz to display plots. Is there a better/quicker interface? Inkscape is great for vector editing of plots, but for most of my usage, I just want something where I can zoom in, look at stuff and save to pdf/svg for including in Latex document later. I was looking into tikzit, but I don’t know how to switch the display to tikzit in julia. TLDR: How to switch interface from inkscape to anything else in Plots.jl, and interface suggestions for that ‘anything else’.

  2. I have this kind of preamble for plotting:

function makePlot(x,y)
    plot(framestyle=[:box, :grid], size=(800,600))
    plot!(x,y,label=:"Label", lc=:red)
    xaxis!("xlabel")
    yaxis!("ylabel")
    title!("title")

    savefig(string(path, "fig1.pdf"))
end

How to have a scatter and line plot together in julia? Python has a parameter in plt.plot where you can specify linestyle as plt.plot(x,y, 'ko-'). In julia, the only attributes are Symbol[:auto, :solid, :dash, :dot, :dashdot, :dashdotdot] . I’ve been using plot!(x,y); scatter!(x,y) together to circumvent this problem.

and

using framestyle throws the following error with pgfplots:

  1. Last question, how to change the grid density in framestyle[:grid]?

Thanks for all the help!

using plot(framestyle=(:box)) instead of plot(framestyle=[:box]) solves one of the problems. I still don’t know how to include minorgrids.
