[FR] Way to modify series labels after plot creation.

[nathanrboyer]

Currently labels have to be added at the same time the series data is plotted. Other attributes like titles and axis labels can be added and modified after the fact. I would like to be able to add and modify the legend after plot creation also.

Ideally, this would be done in the same way as other attributes like plot!(labels=stringarrayoflabels), but a new function like labels!(stringarrayoflabels) could work too.

This would be most helpful to me when a plot is created within a function, but I want to be able to pretty it up outside of the function to avoid passing a lot of variables back and forth.

There is no official API, but you can already do this via

p = plot(1:5)
p[1][1][:label] = "label"
p

Is #2880 supposed to work? The proposed method does not work for me.

That only worked for some cases, but not in general.
