For a talk at https:\/\/cuttingeegx.org\/<\/a> I tried to push what Julia \/ https:\/\/makie.org\/<\/a> can do for me on this issue. I wanted to have a quite complex plot, that I’d typically do in Illustrator, completely in Julia – and succeeded \ud83c\udf89<\/p>\n\n\n\n

Figure was 100% plotted via Julia \/ Makie.jl \/ MakieTex.jl<\/a><\/figcaption><\/figure>\n\n\n\n

What follows is a short tutorial on how I plotted the matrix. Note that in the following I am using typst<\/a> rather than LaTeX – a sane, modern, open-source replacement.<\/p>\n\n\n\n

\n\n\n\n
using MakieTeX, CairoMakie,Format\n\n# convert a list of matrices to a typst-matrix\nfunction gen_typst_matrix(str,args...;)\n\t# for convenience, we define a new typst command\n\tout = typst\"\"\"\n\t#let cm(x, color) = text(fill: color)[$#x$];\"\n\t$mat(delim:\\\"[\\\",\n\t\"\"\"\n\tpayload = format.(str,args...)\n\tfor k = 1:size(payload,2)\n\t\tout = out * join(payload[:,k],',') * \";\"\n\tend\n\tout = out*typst\")$\"\n\t\nend<\/code><\/pre>\n\n\n\n
Next we define some colors and a color-conversion function<\/p>\n\n\n\n
rgba_to_typst(c) = format(\"rgb({}%,{}%,{}%,{}%)\",c.r*100,c.g*100,c.b*100,c.alpha*100)\nend\n\ncolorlist = cgrad(:batlow,10;categorical=true)|>collect\n\n<\/code><\/pre>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
Next we convert a matrix to Typst & add the color using our predefined cm<\/code> command<\/p>\n\n\n\n
typst_mat = gen_typst_matrix(\n\"cm({:.1f},#{})\",\nrand(Int,8,5),\nrepeat(rgba_to_typst.(colorlist),1,5))\n<\/code><\/pre>\n\n\n\n
Now we use the MakieTex function LTeX<\/code> to convert it from Typst to PDF to Makie<\/p>\n\n\n\n
LTeX(TypstDocument(typst_mat),scale=3); # scale = 3 to fill the figure<\/code><\/pre>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
Tada \ud83c\udf89<\/p>\n\n\n\n
We can also combine this figure easily with other Typst things e.g.<\/p>\n\n\n\n
LTeX(fig[2,1],TypstDocument(typst\"$lambda = rho \/ phi$\"),scale = 3)\n\n<\/code><\/pre>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
or of course, a plot<\/p>\n\n\n\n
r = 0:0.1:10 .*\u03c0\nax = lines(fig[1:2,2],r.*sin.(r),r.*cos.(r),color=r)\nhidespines!(ax.axis);hidedecorations!(ax.axis)\n<\/code><\/pre>\n\n\n\n
