[英]Plot several graphs with R igraph
I would like to draw two graphs g1
and g2
on the same plot with the R
version of igraph
.我想用
igraph
的R
版本在同一个图上绘制两个图g1
和g2
。 However, if I just apply the plot
(or plot.igraph
) function twice, I just get two separate plots.但是,如果我只应用
plot
(或plot.igraph
)函数两次,我只会得到两个单独的图。 Is there a way to have both graphs drawn on the same plot?有没有办法在同一个图上绘制两个图形?
Here's some minimal code:这是一些最小的代码:
library(igraph)
g1 <- barabasi.game(10)
g2 <- barabasi.game(5)
plot(g1)
plot(g2)
Edit: I want both graphs to be plotted in the same figure.编辑:我希望两个图都绘制在同一个图中。 So, one node from
g1
and another one from g2
could very well overlap in this figure, if they hold close spatial positions in their respective graphs.因此,如果
g1
一个节点和g2
另一个节点在该图中很可能重叠,如果它们在各自的图中保持接近的空间位置。
Try this:尝试这个:
library(igraph)
g1 <- barabasi.game(10)
g2 <- barabasi.game(5)
plot(g1)
plot(g2, edge.color='black', vertex.color='green', add=T)
The main trick here is to use add=TRUE
while plotting the second graph.这里的主要技巧是在绘制第二个图形时使用
add=TRUE
。
I have changed the color of edges and vertices of g2 to be able to tell g2 apart from g1 .我已经更改了g2的边缘和顶点的颜色,以便能够将g2与g1 区分开来。
we can use par(mfrow=c(1,2)), and write add=TRUE in 2nd plot.我们可以使用 par(mfrow=c(1,2)),并在第二个图中写 add=TRUE。
library(igraph)
par(mfrow=c(1,2))
g1 <- barabasi.game(10)
g2 <- barabasi.game(5)
plot(g1)
plot(g2,add=TRUE)
