Dear all,
I
would like to depict a network with Ring/Donut Shaped Vertices. I did not
find such a shape in Igraph documentation, but I found a pie shaped
instead. Like the following code (and the resulting attached figure):
library(igraph)
g
<- make_ring(10) values <- lapply(1:10, function(x)
sample(1:10,3)) if (interactive()) { plot(g, vertex.shape="pie",
vertex.pie=values, vertex.pie.color=list(heat.
colors(5)), vertex.size=seq(10,30,length=10), vertex.label=NA) }
Do
you know a way of turning a pie shaped vertex into a ring/donut shaped vertex
using Igraph itself? I searched for a "vertex.pie.hole" parameter, but it does not exist. The easiest way I see to do this is to depict
"white points" in the centroids of the vertices, but it is clearly not
an ideal situation.
I know it is possible to define our own vertex shape, but I must confess it is been really hard for me to do this for a ring/donut shape.
