Re: [igraph] plot.igraph and x-axis

[Hermann Norpois]

I am sorry I did not get it.
If I use rescale=FALSE my plot is empty.

Actually I would like to change the rescale parameters. Is that possible, i.e.

rescaleparameters = V(gs)$x

My try:
plot (gs, vertex.size=2, vertex.label=NA,rescale=FALSE, edge.width= (E(gs)$weight)^6, layout=cbind (V(gs)$x, V(gs)$y))

> dput (gs)
structure(list(2, FALSE, 1, 0, 0, 0, c(0, 0, 1), c(0, 1, 1),
    list(c(1, 0, 1), structure(list(), .Names = character(0)),
        structure(list(name = c("rs744016", "rs763273"), x = c(27042106L,
        27043594L), y = c(0.6445235948615, 0.6229189950958)), .Names = c("name",
        "x", "y")), structure(list(weight = 0.986597, y = 0.7704755,
            color = "red"), .Names = c("weight", "y", "color"
        )))), class = "igraph")

Hi,

no, this is an igraph thing, igraph rescales layouts to (-1, 1),
unless you specify the rescale=FALSE:
