+# Multiple graphs on one page

+

+To support viewing multiple plots, ggtree provides `multiplot` function that similar to `gridExtra::grid.arrange` with extra feature of labeling the plots.

+

+

+```{r fig.width=8, fig.height=4, warning=FALSE}

+multiplot(ggtree(rtree(30)), ggtree(rtree(40)), ncol=2, labels=c('A', 'B'))

+```

 # subplots in ggplot object

 `ggtree` implemented a function, `subview`, that can add subplots on a ggplot2 object.
