I'm sorry. I should have been more explicit. Gnuplot runs and creates
the necessary output file(s) which starts with the following for
example:

% Written by ConTeXt terminal for GNUPLOT on: 2013-01-21 01:17 CET
% GNUPLOT version: 4.6.1, terminal version: 1.0.0 (2011-11-05)
% See also http://wiki.contextgarden.net/Gnuplot
%
\startGNUPLOTgraphic[1]
string gnuplotversion; gnuplotversion := "4.6";
... <metapost code here>


The command \useGNUPLOTgraphic[foo] basically calls
\reuseMPgraphic{gpg:foo:1} where "foo" is the name from brackets and 1
is the sequential number.

But instead of the graphic I get the following written to the pdf as text:

% Written by ConTeXt terminal for GNUPLOT on: 2013-01-21 01:17 CET % GNU-
PLOT version: 4.6.1, terminal version: 1.0.0 (2011-11-05) % See also
http://wiki.con-
textgarden.net/Gnuplot %

If I change the graphic to TikZ, I get almost the whole plot, except
for the sine line which is drawn between -10 and approximately -9 and
then disappears. I suspect the culprit is the percentage sign at the
end of the line:

\draw[gp path] (1.410,5.722)--(1.517,5.147)--(1.625,4.524)--(1.732,3.879)--(1.840,3.237)%
  --(1.947,2.626)--(2.055,2.070)--(2.162,1.591)--(2.270,1.210)--(2.377,0.941)--(2.485,0.795)%
  --(2.592,0.779)--(2.699,0.893)--(2.807,1.133)--(2.914,1.488)--(3.022,1.944)--(3.129,2.484)%
... 17 lines altogether
  --(11.618,4.718)--(11.726,4.076)--(11.833,3.431)--(11.941,2.808)--(12.048,2.233);

I didn't test it, but it seems as if everything after the first
percentage sign gets ignored.

I can do a couple more tests with MetaPost and TikZ in \asciimode, but
the fact that the above line gets broken in the middle simply doesn't
seem right (even if my gnuplot module code is clumsy).
