Constant layout orientation in igraph

Question

[saamar.rajput]

I am drwaning graphs in igraph using the "layout_with_dh" layout, but everytime i generate the graph the orientation is changed. Is there a way to keep the same orientation of the graph as i would be looking at the graph for different timepoints so I want them to look the same.

Try setting the random number generator seed with set.seed(). For example:

library(igraph)
g <- barabasi.game(10)
set.seed(123)
plot(g, layout = layout_with_dh)

The best approach for dynamic graphs is to fix the node positions after running one of the layout algorithms on one instance of the graph. You can get the coordinates from the corresponding igraph layout function, e.g.:

coords <- layout.davidson.harel(g)
plot(g, layout = coords)

This means you can also manually tweak the coordinates to your liking.
