z-order of Gnuplot functions or order in key

Question

You can change the z-order of two functions plotted together by reordering the order they appear in the plot function, but this also changes the order in the key. Is there a way to reorder either the order the function appears in the key or the z-order independently of the order it appears in the plot function?

Answer 1

If you can get the z-order you want by simply reversing all the functions you can do

set key invert;

to reverse them in the key.
