Updating labels with plot!

[joshday]

At least for Gadfly and PyPlot backends,

This works as expected:

plot(randn(100,2), label = ["one" "two"])

Whereas this does not:

plot(randn(100,2))
plot!(label = ["one" "two"])

Would it also be possible to allow label to accept a Vector?

Both requests might be tough, though I can see why you want it. Series are made in one pass, although you can update plot-wide settings after the fact. I'll brainstorm on it a little, but it would probably require a redesign of some core pieces. Something like an "update series" mechanic (which would be good to have in general). I'll keep you posted.

As for Vector vs Matrix... I don't think I'm going to change that, as it's important for distinguishing between vectors that apply to all series vs matrices that map a column to a series.

Ah, I didn't realize that distinction between giving an argument a Vector vs. Matrix. That makes sense.

[tbreloff]

I thought about it, and I'm going to do a slight redesign to make it easier to update series (and improve some other stuff along the way).

6 months later...

It's not perfect, but it works for me:

using Plots
p = plot(rand(10), size=(300,300))

p.series_list[1].d[:label] = "Look ma... a new label"; p
