在 Igraph 中绘图时仅显示 x 轴（在 R 中）

Question

I'm doing network visualization with igraph in R. I want to display a chronological order on the x-axis, the values on the y-axis will be set manually in order "even them out" over the plot, ie the numbers on the y-axis contains no information of use for the reader. Hence, I want to only display the x-axis, not the y-axis.

Here is a demonstration on my current status.

library(igraph)

#graph from dataframe
from <- c("One", "Two")
to <- c("Three", "Three")
fromto <- data.frame(from,to)
fromtograph <- graph_from_data_frame(fromto)

#df with coords
year <- c(400,500,600)
coords <- data.frame(as_ids(V(fromtograph)), year)
coords <- coords[order(match(coords$as_ids.V.fromtograph.., as_ids(V(fromtograph)))),]
coords <- as.matrix(data.frame(coords$year,c(300,100,200)))

plot(fromtograph,layout=coords,rescale=F,axes=T, ylim=c(0,400),xlim=c(0,800),asp=0)

The plot results in this .
I want this

Answer 1

I would add a filled (white) rectangle over y-axis.

plot(fromtograph,layout=coords,rescale=F,axes=T, ylim=c(0,400),xlim=c(0,800),asp=0)
rect(-100, -10, 0, 450, col = "white", border = "white")
