Please briefly describe your problem and what output you expect. If you have a question, please don't use this form, but instead ask on the mailing list https://groups.google.com/forum/#!forum/ggplot2 or stackoverflow http://stackoverflow.com.

Please include a minimal reprex. The goal of a reprex is to make it as easy as possible for me to recreate your problem so that I can fix it. If you've never heard of a reprex before, start by reading https://www.tidyverse.org/help/#reprex, and follow the advice further down the page. Do NOT include session info unless it's explicitly asked for, or you've used reprex::reprex(..., si = TRUE) to hide it away.

Delete these instructions once you have read them.
