I’m struggling to figure out how to use a slider to interact with an animation in Makie.
I’m using v1.1.1 in Atom under Win10. The code below is MWE using animation. The hexagons move across the plot while dot changes color from blue to yellow with random probability proportional to the height of the second hexagon.
I want to control the x-position of the hexagons using the slider, and have the dot continue to change color randomly even if the slider is not sliding. I’ve looked at the slider examples in the Makie gallery but can’t figure out how to generalize to my problem. Also can’t find documentation about e.g. RecordEvents (what is the string in the second argument? It seems to be essential but what is it for?).
using Makie using AbstractPlotting using Colors x₀ =-5. gateState = false xRange = 10 # deflection p₀(x) = x/2 # plot nPts = 100. x = (x₀ .+ collect((-nPts/2.):(nPts/2.))/nPts*xRange) scene = lines(x, p₀(x), linewidth =4, color = :darkcyan, leg = false ) axis = scene[Axis] axis[:names][:axisnames] = ( "x","y") HC_handle = scatter!([-4], , marker=:circle, markersize = .5, color = :red)[end] s1 = slider(LinRange(-5.0, 5.0, 101), raw = true, camera = campixel!, start = -5.0) kx = s1[end][:value] scatter!(scene, [kx; kx],[0.5; p₀(kx)], marker = :hexagon, color = RGBA(.5,0.,.5,.5), markersize = .35, strokewidth = 1, strokecolor = :black) Kc_handle = scene[end] record(hbox(scene, s1, parent = Scene(resolution = (800, 600))), "gate.mp4", 1:200) do i Δx = x₀ + 0.05*i p = p₀(Δx) gateState = rand(1)<(p + 2.5)/5 HC_handle[:color] = gateState ? :gold1 : :dodgerblue1 Kc_handle = [Δx, Δx] Kc_handle = [0, p] end
