###网络图构建
df=read.csv("data.csv")
df$Breeding.time=factor(df$Breeding.time,levels=unique(df$Breeding.time))
p2 <- ggplot(df, aes(Breeding.time,number.of.nests,group=species,col=species)) + 
  geom_step(aes(linetype=species),size=1)+
  theme_classic()+
  theme(
        legend.title=element_text(size = 12),
        legend.text=element_text(size = 12),
        axis.text.x = element_text(size = 12), 
        axis.text.y = element_text(size = 12))+
   labs(x="a",y="b")
p2
