+You can set title, subtitle and axis' titles at once with `ax_labs()`:
+
+```{r}
+apex(data = n_cut, type = "column", mapping = aes(x = cut, y = n)) %>%
+  ax_labs(
+    title = "Cut distribution",
+    subtitle = "Data from ggplot2",
+    x = "Cut",
+    y = "Count"
+  )
+```
+
+If you more control (font size, alignment, ...), you can use `ax_title()`, `ax_subtitle()`, `ax_xaxis()` and `ax_yaxis()`, as described below.
