[Gnuplot-py-users] No monochrome png and title-offset

Hi,

I am running gnuplot 4.0 and it seems to be imposible to create an monochro=
me=20
png:
this line:

g.hardcopy("somename.png", terminal=3D'png', monochrome=3D 1)

gives me:

gnuplot> set terminal png monochrome
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 ^
=A0 =A0 =A0 =A0 =A0line 0: invalid color spec, must be xRRGGBB

=46urthermore I would like to know how I can move the description line (the=
=20
title) for a plot like this:
g.plot(Gnuplot.Data(tmp1, title =3D "C^1_{t}", with=3D"lines"))

this:
g.plot(Gnuplot.Data(tmp1, title =3D "C^1_{t}", with=3D"lines", offset =3D (=
1,1))
does not work for me.

Thank you very much,

Daniel
