I have a very long plot that I'd like to split into several sub-plots to make it readable.
To my data.frame, I added an additional variable to make sub-groups for wrapping and used facet_wrap to make multiple plots. However, due to the 'free_x' scale, the last plot looks weird. I want it to have the same x:y ratio with the space at the right being just blank.
@nirgrahamuk , as a workaround I would rather add NA values at the end of the tibble not to mess up with x-axis labels (they are still meaningful even after wrapping). With the default color scale it assigns grey to NAs so needs to be fixed, but works perfectly with viridis scales.
I actually was wondering if there is a way to do it with the ggplot functionality.
