The Interface conventions of TeXmacs assume that after every input
line an output field is produced and shown. To obey this rule the
gnuplot interface (see the script "tm_gnuplot") uses the "~" character
to separate input-parts that normally would be written as ("newline"
separated) lines.

so typing


     Gnuplot] set xlabel 'x:[cm]' ~ plot exp(-x**2)

should work for your example.
