I am trying to make some 'close stacked' plots using Cowplot. I can get the effect I want using the following MWE:
library(ggplot2)
library(cowplot)
disp_plot <- ggplot(data=mtcars,aes(x= hp,y=disp)) + geom_point()+
theme(plot.margin = unit(c(0.3,0.3,0.0,0.15), "cm"),
axis.text.x =element_blank(),axis.title.x =element_blank())
mpg_plot <- ggplot(data=mtcars,aes(x= hp,y=mpg)) + geom_point()+
theme(plot.margin = unit(c(0.0,0.3,0.0,0.15), "cm"),
axis.text.x =element_blank(),axis.title.x =element_blank())
qsec_plot <- ggplot(data=mtcars,aes(x= hp,y=qsec)) + geom_point()+
theme(plot.margin = unit(c(0.0,0.3,0.3,0.15), "cm"))
mp <- plot_grid(disp_plot, mpg_plot, qsec_plot,ncol = 1,align='v', axis = 'l')
Notice that mpg is not the same vertical scale as the others. To get the plots to be the same vertical size as well, I'd like to use "align='hv'" in plot_grid. However, this causes the spacing set by the margins to revert and the figures fly apart again. Is there a way I can preserve my spacing?
