Volcano data

Animation
An animation can be produced by pushing new plots into an existing plot, and then saving the result as a GIF the the animate
option.
closeall() #hide
t = 0:0.01:2π
f(t,i) = sin.(t .+ i/10)
ac = Axes(title = :Animation, xlabel = :x, ylabel = :y); # axes configuration
cc = "w l lc 'black' notitle" # curve configuration
F = plot(t, f(t,1), curveconf = cc, ac); # create the first frame, with handle 1
for i = 2:50
pi = plot(t, f(t,i), curveconf = cc, ac, handle=2) # frames, with handle 2
push!(F, pi) # push the frame to F
end
