Hi Guangchuang ggtree is awesome! I have a ggtree object and a ggplot object. How to overlap these two? No need to care about the labels. I just want map two plot together not combine two side by side like using patchwork.

You can use the tree layer function geom_tree to add tree layers to ggplot objects.
