Error Plotting

New to Julia

I am trying to plot a Vector of arrays,

θₜ=Vector{Float64}[]

It has 29 arrays of 100 elements each, and when I try to plot using the following, it throws an error:

using Plots
plot(1:1:29,θₜ[1:1:29],legend=false)

Error showing value of type Plots.Plot{Plots.GRBackend}:
ERROR: BoundsError: attempt to access 29-element Array{Float64,1} at index [1:100]

What am I doing wrong?

Well, what do you want your plot to be? 100 lines of 29 points each or 29 lines of 100 points each, plotted against what?

Right now the translation of your command would be “x = numbers 1 to 29, y = 29 times 100 points”. I wouldn’t know what to do with that and I suspect Plots.jl feels the same way.

I would want 100 lines of 29 points each.

You could do this with

x = hcat(θₜ...)
plot()
foreach(r -> plot!(1:29, r), eachrow(x))
