I have  in a plot 17 keys the bottom one of which disturbs the data lines. I try to change the height using
set key height 10
It is divided to two columns but leaves a lot of white space above and below the keys when the box is drawn and is difficult to align it in the plot.

My question is: is it possible to specify the  exact height of the keys?

Any reply is welcomed.
Best regards!
