Increase ggplot after build / view

I am making charts in batch. When viewing graphs, it would be helpful to zoom in on the serval areas. Is there a way to scale / scale the axis after creating the plot and then restore it back to its original axis range?

Answer, after incorporating feedback and comments ....

set.seed(5)
gplist<-list()
for (i in seq(1,29)) {
  mod_evt = paste("plot",i)
  df <- data.frame(x=runif(10), y=runif(10))
  gp <- ggplot(df,aes(x=x,y=y)) + geom_line() + geom_point() +
    labs(title = mod_evt, x="X", y="Y") 
  print(gp)
  gplist[[i]] <- gp
}

      

I would like to scale up this drop around x = 0.52 on graph 27

print(gplist[[27]] +  coord_cartesian(xlim= c(.5,.6)))

      

This reproduces a plot with the x-axis zoomed between .5 and .6.

Yes, using coord_cartesian

(or appropriate coord_xxxx

)

ex <- ggplot(mtcars, aes(x=mpg,y=drat, colour=factor(cyl))) + geom_point()

ex

      

enter image description here

# plot with "zoomed region"
ex + coord_cartesian(xlim = c(10,25),ylim= c(3,5))

# the original still exists

If you have a list of charts

 plot_list <- list(ggplot(mtcars, aes(x=mpg,y=drat, colour=factor(cyl))) + geom_point(),
                   ggplot(mtcars, aes(x=mpg,y=drat, colour=factor(am))) + geom_point())
 zoomed <- lapply(plot_list, function(p) p + coord_cartesian(xlim= c(15,30)))


 # or for a single plot
 plot_list[[1]] + coord_cartesian(xlim= c(15,30))
