I am not aware of any plot parameter which would allow flipping the axis, 
but you can transform the data to be flipped and use an axis transform for 
the axis itself.  I wrote a blog post which is somewhat related: 
https://alex-hhh.github.io/2020/02/dual-axis-plots.html, the post covers 
plotting a second data series which has a different scale than the first. 
The same technique of making "guest" transforms can be used to flip an 
axis: you would call 
(make-guest-transform base-min base-max base-max base-min) to obtain the 
"flip" transform and only plot the "guest" which would be flipped.

Hope this helps,
