I’m having this issue while doing this visualization. The color of some markers are supposed to be red instead of black. Could you please help me how to fix this?
Here is my code
using Plots using Random n = 5 mypoint = (rand(1:10, n), rand(1:10, n)) mybool =  push!(mybool, BitVector(undef, n)) push!(mybool, bitrand(n)) anim = @animate for v in mybool scatter(mypoint, markersize=10, c = map(x -> x ? :red : :green, v)) end gif(anim, "point.gif", fps=1)
I can reproduce this, and it’s weird.
Just to get the obvious things out of the way, you can use
falses to initialize a zeroful BitArray, so
mybool = (falses(n), bitrand(n))
The problem still appears here.
colors = (fill(:green, n), rand([:red, :green], n)) anim = @animate for v in colors scatter(mypoint, markersize=10, c = v) end
shows the same issue.
colors = (rand([:red, :green],n), rand([:red, :green], n))
does not, unless the first vector is all the same color.
colors = (rand([:red, :green],n), rand([:red, :green, :blue], n))
makes the points in the second plot which should be blue gray.
The first frame in an animation sets the gamut, and any other colors in subsequent plots are replaced by gray. I would have suggested a bug report to
Plots.jl, but I see you already have.
Could this be related to the implementation of this idea in
ffmpeg_exe with the new setting:
