+Please briefly describe your problem and what new feature you would like to be implemented in future versions. If you have an ordinary question, please don't use this form, but instead ask on stackoverflow <http://stackoverflow.com> using tag [ggpmisc] or possibly [ggplot2].
+
+If possible, please include a minimal example of the desired interface and a sketch of the wished plot output. The goal of an example is to make it as easy as possible for me to understand what you are missing and to make sure that it is not something that is already possible to do in some other way.

+Please briefly describe your problem and what output you expect. If you have an ordinary question, please don't use this form, but instead ask on stackoverflow <http://stackoverflow.com> using tag [ggpmisc} and optionally [ggoplot2].

+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.

+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 or help you find a solution. 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.  Please, if at all possible use data that is already available in R or a CRAN package, or simple artificial data generated within your scripts. Include in your reprex the code needed to load data and packages. The example should be as simple as possible and should run on a clean/fresh R session.
