Plot inside a loop again[, but now in Pluto]

using Plots;plotly()

begin
	plot()
	for i = 0:0.1:1
		vline!([i], leg = :none)
		sleep(0.01)
	end
	#plot!()
end

I want to the plot for for each iteration of the loop.How can I do it?

This works fine for me:

begin
	p = plot()
	for i = 0:0.1:1
		vline!(p, [i], leg = :none)
		sleep(0.01)
	end
	p
end

If I understand OP correctly, he wants to show the plot in each iteration? I.e. this:

p = plot()
for i = 0:0.1:1
	vline!(p, [i], leg = :none)
	sleep(0.1)
	display(p)
end
p

(note the display call), which works fine for me in Juno, but not in Pluto for some reason.

In that case I would probably take advantage of Pluto’s reactive nature and create a Slider(0:0.1:1) via PlutoUI and then view the plot that way…

T = 0:0.1:1

@bind N Slider(eachindex(T))

let
p = plot()
for i = T[1:N]
	vline!(p, [i], leg = :none)
end
p
end

That is a great of doing the plots, but I want to plot live data. The solution here does my job what if I want to display the plots before the all the loops are computed ?

A simple use case is gradient descent. We want to plot live data of loss v/s epoch of the model being trained. Based on the live graph we can decide whether to continue or stop the rest of the computation.

Is there any way I can do it ?

I wrote a minimal demo about this once:
