Facet_wrap常见图例

Question

我想制作一个facet_wrap，同时在有意义的地方有一个共同的传说。我的意思是，我希望A. gueldenstaedtii在两个图中都具有相同的符号。巴氏曲霉也是如此。 在问这个之前，我还尝试过grid_arrange_shared_legend和plot_grid。

当我运行下面的代码时，我得到了两个A. gueldenstaedtii和A. baerii。我只想要1 A. baerii和1 A. gueldenstaedtii。

g<-ggplot(data = amp,aes(x = Cycle, y = `Fluorescence (dRn)`, colour=`Species`,group=amp$merge))+
  geom_line()+
  geom_point()+
  theme(text = element_text(size=16), axis.text.x = element_text(size=16),axis.text.y = element_text(size=16) ) +
  theme(legend.direction="horizontal",legend.position="top", legend.box = "vertical")+
  facet_wrap(~Run, ncol=2, scales = "free")
g

以下是一些示例数据
