Alpha modifier

[KronosTheLate]

I am often in the situation where I just want to add some alpha (transparency) to a plot, without making changes to colors. So I would like to use the default colours, or one specified with Cycled, but with some alpha != 1.. However, I have been unable to find a way to do this without manually specifying a color.

Perhaps it would be feasable to add field "alpha" to Cycled? It could then be Cycled(1, 0.5), analogus to (:black, 0.5).

My band-aid fix ended up being color=Makie.wong_colors(alpha)[i], which worked well. But it uses a non-exported function, and it quite verbose, and so it feels hacky.

nowadays a lot of plot objects take an alpha keyword, does that help?

[KronosTheLate]

Oh wow, yes! I did not realize that I could change it for the plot object like that, this is exactly what I was looking for.

I guess the fix then is just to document this in the docs, and possibly at the top. Definitively before the "problems with transparency" at least. I imagine that this will be the most ergonomic way for most poeople to quickly change the transparency.
