Reversing the y axis on discrete data-CodePudding

I have a chart built with ggridges, as below, for which I would like to reverse the date order:

To do this I've added the c_trans() function, as defined which is clearly not what I want. Is there any way to reverse the y axis but keep it discrete?

Input data:

> lengthCounts2
# A tibble: 8,724 x 5
# Groups:   date, rwi [6]
   date                rwi     len       n normalised
   <dttm>              <chr> <dbl>   <int>      <dbl>
