How to make an horizontal box-and-whiskers plot in gnuplot

Question

How do you make an horizontal box-and-whiskers plot in gnuplot? Similarly to this one:

Gnuplot can easily be used to produce vertical box-and-whiskers plots with the 'candlesticks' and 'whiskerbars' keywords, but I have not managed to find any example of an horizontal candlesticks/box-and-whiskers horizontal plot produced via gnuplot online.

Example of a vertical plot produced by gnuplot:

Answer 1

Gnuplot generally doesn't switch directions well... for example you can't plot rows instead of columns, and it's hard to make histograms (or any other kind of plot) go horizontal instead of vertical.

People have made horizontal histograms, however, and you might be able to modify the code found at this site.
