For publication purposes, I am interested to create a `monochrome` plots. In particular, how could I implement a monochrome theme in `Plots` (or in any other package) , similar to the `Monochrome` theme of `Mathematica`?

Use one of the monochromatic palettes as described on [ColorSchemes · Plots](https://docs.juliaplots.org/latest/generated/colorschemes/).
For example:
```julia
julia> function f(x, y)
r = sqrt(x^2 + y^2)
return r
end
f (generic function with 1 method)
julia> x = range(-10, 10, length = 30)
-10.0:0.6896551724137931:10.0
julia> heatmap(x, x, f, c = :grays)
```

Thanks for your recommendation.
However, this solution does not fit into my needs. I am plotting two linear functions. When I use one of the `gray` palettes you mention the result is that either the color of one function is white, or both two functions have quite the same color.
Also, Mathematica’s `monochrome` theme is different. The first line is straight, the second is dashed, the third is dotted, and so on…

For a specific subset of (for example) the grays gradient, see the colorpalette section of the page linked above, or define your own palette with a vector of colors.
I would imagine you can then edit the style of each series with :linestyle as [seen here](https://docs.juliaplots.org/latest/generated/attributes_series/). I’m not entirely sure how to do that for a set of series, but it’s probably just a vector of symbols.
If you wanted to collect all of that together into a theme you could use on multiple plots, you could define your own theme, as seen [here](https://docs.juliaplots.org/latest/generated/plotthemes/). I don’t think that would take much effort, the framework there is really quite nice! I think a PR for that theme if you put some work into it would be appreciated by the Plots.jl team too.

This theme is definitely something that would be nice to have. I can see you’ve opened an issue on PlotThemes that unfortunately received no traffic.
Just for what you are doing there, how does `linecolor = :black, linestyle = :auto` work?

thanks, i will give it a try asap
