Thank you, for this post, I didn't knew about theme_void() I think I will use it from now on.
I got a question, the hjust = 0.5 is the code that put the title in top center positions I guess, but what it means the vjust = 0.5 in geom_text().
I mean I imagine is what puts te labels inside the pie sections. But does it work vjust in that particular case!
Thanks
