I'm trying to improve a simple but important detail in my facet\_grid graphic.

I played with scale and space parameteres of facet\_grid() function. But I would like to increase the height **only for** the bottom facet in order to be possible to read the sample count that appears cut off in the graph (highlighted in red). See Image1.
The code used is:

```
    ggplot(salm_data, aes(x=SALM) ) + geom_bar(stat = "count", position = position_dodge())
 + facet_grid(YEAR ~ TYPE, scales = "free_x", space = "free") 
 +  geom_text(size=2.5, stat = "count", aes(label = after_stat(count)), vjust = -0.3) +theme_bw() + labs(y="Number of samples") + 
theme(panel.grid.minor = element_blank())+
 labs(x=expression(paste(italic("Klebsiella spp."), " ")))

```

To try to overcome this "problem" I tried including next code to enlarge the Y-axis:

```
scale_y_continuous(breaks = seq(from = 0, to = 300, by = 40))

```

But I'm not capable to improve the situation (see Image2).

Could you help me with some ideas to overcome this scenario?

Thanks on advance for your help/comments,
