Reverse order of discrete y axis in ggplot2

Solution 1:

There is a new solution, scale_*_discrete(limits=rev), example:

tibble(x=1:26,y=letters) %>% 
  ggplot(aes(x,y)) +
    geom_point() +
    scale_y_discrete(limits=rev)

enter image description here

as per https://gist.github.com/jennybc/6f3fa527b915b920fdd5:

add scale_y_discrete(limits = rev(levels(theFactor))) to your ggplot command.

For a discrete axis, using reorder() worked for me. In context of the above problem, it would look something like this:

ggplot(df, aes(x = distanceRemaining, y = reorder(position, desc(position))))

Hope this helps.
