The matrix itself is fine, the columns being x, f(x). The thing is that gnuplot expects the y-axis variable(s) to be given first, then x (this is in the help for the "gnuplot" command). Maybe if you use "gnuplot" on a two-column matrix without giving a list for the column order we should assume the matrix is in x, y order and therefore reverse the columns for gnuplot's benefit? I'm not sure if that would break any build-in uses of gnuplot in gretl.
