Plots.jl: Proposal for main contributors

[juliohm]

Could someone already involved with the codebase perhaps host a webinar or record a video going over the machinery in Plots.jl in an attempt to educate potential contributors?

I am particularly interested in tackling all the issues tagged with GR because that is my favorite backend. However, I currently don't have the time to learn how Plots.jl does things internally, the layers of abstraction, etc. If I had a "push" from someone that could explain the details, I could keep going by myself.

There is a rather old video from tbreloff. Giving an overview of Plots.jl internals, have you seen that one?

It's a good idea, if it leads to people like you having an easier time contributing. One thing to appreciate at length is this call graph, showing what happens when you call histogram(x). Notice half the work is done by display, which gets automatically called when you return a Plot object to the console.

Sorry, wrong link - here's the right one: https://drive.google.com/open?id=0BwWjA0Ez4iLhdERRRVlHekZiejA

[mkborregaard]

Here's the good thing: plot calls are largely identical, so once you know this call graph well you'll know it all.

Thank you @apalugniok, where is the link?

Thank you @mkborregaard, we definitely need someone going through the internals in a video or something, this call graph is insane :flushed:

https://www.youtube.com/watch?v=Iof7Ccm8UiM here you go! It's pretty high level though 😟

[juliohm]

Yes, it would be great to have something more specific like fixing an issue with one backend for example.

[mkborregaard]

There's also this http://docs.juliaplots.org/latest/contributing/
The answer to that last question is to go to the code for that backend and fix it :joy:

I think what I will do is start watching the PRs. If you could explain the changes in the PR description at least, that would be already a good addition to the documentation.

It would be great to have a CONTRIBUTING file explaining that all PRs could contain a careful explanation of the changes, what the issue was and how it was solved.

I will close this one and follow the repository.
