When I type “?surface” into the REPL, I get the following: ... Example ≡≡≡≡≡≡≡≡≡ julia> x = y = range(-3, 3, length = 100) julia> surface(x, y, (x, y) -> sinc(norm([x, y]))) This example generates the following error: “UndefVarError: norm not defined” Changing it to hypot does not help, becau…

FYI I have made the PR here: Add LinearAlgebra to make example with `norm` work by nilshg · Pull Request #2504 · JuliaPlots/Plots.jl · GitHub @TheLateKronos in this case as Tamas said it was enough to use the GitHub web interface - click Fork on the Plots repo (top right corner), then navigate to t…

[image] TheLateKronos: Can this be fixed asap? You may not realize this, but asking that something, especially a trivial doc issue, is fixed “asap” in a free software project just strikes the wrong tone. In this particular case, the best fix may be just adding using LinearAlgebra, which has n…

[image] TheLateKronos: surface(x, y, (x, y) → sinc(norm([x, y]))) That worked well! Thanks. When I tried changing norm into something that was defined (like hypot, which I though would do something similar) and it still did not work, I figured something bigger was wrong. My bad. The reason f…

[image] TheLateKronos: it would just be editing the right text file, which is a small enough thing to do to just do. I have never used github In this particular case you can just click through buttons on Github to edit the docstring on a web interface and make a pull request that way. [im…

Yhea I know it is far from a tall order generally in programming, but we are only 7 months into a physics-bachelor so programming is really new to most. And when starting something like a new language, small problems can feel enourmus when you have not seen them before. I’ll try and make that pull…

So I tried to figure out how to make the pull-request myself. It seems I have to download the file for the package from GitHub, make the change I want, and re-upload. Is that right? I tried locating the docs-file, but I can’t find it. Also I am not sure if the example should be updated, or a note ab…

Thanks for your patience. I will definitely do this myself next time I want to commit anything.

Looks perfect, thanks a lot. Tried navigating through and it all seemed okay to do myself next time. One question though - how did you locate the help-tip for “surface” in “shorthands”? I had no idea where to look for the file, and got lost quickly myself.

Top left corner, the search box - if you type something into it, the default search will search in that repo only. So simply searching for sinc(norm([x, y])) was enough

Ofc, searching for something you know to be in the location you are looking for. Nice, thanks!
