node coloring failed with over 197 nodes #87

Open hldwn opened 5 years ago

hldwn commented 5 years ago

using LightGraphs, GraphPlot; using Colors;

n = 198 graph = barabasi_albert(n, 3, 3)

mapping = ones(n) mapping[1:100] .= 2

nodecolor = [colorant"green", colorant"red"] nodefillc = nodecolor[convert(Array{Int}, mapping)] gplot(graph, nodefillc=nodefillc)

--> all nodes are black if n<197 --> nodes are green and red

I have a same problem.

On Jupyter Lab, 

using Colors
using LightGraphs
using GraphPlot

node_colors_2 = [colorant"lightseagreen", colorant"orange"]
function plot_graph(n)
    circle = cycle_graph(n)
    actions = fill(2, n)
    nodefillc = node_colors_2[actions]
    gplot(circle, layout=circular_layout, nodefillc=nodefillc)
end

When n=99, the color of all nodes is orage, but when n=100, all nodes are black.
