To be quite honest, I'd recommend that for scientific plotting with python,
you look into matplotlib. While I am a heavy user of scipy's many good
features, I think plotting is not its strongest point. Matplotlib is a
modern, excellent plotting library, directly usable as a WX widget, and which
can produce on or off-screen plots in most formats you are likely to need.
While it may still have a few rough edges, it is under active development and
the remaining (very minor) issues will be quickly ironed out, I think.

Gnuplot's rendering model is terminal-dependent, and gnuplot makes no attempt
to have the plots look the same across terminals. This is explained in detail
in gnuplot's documentation.
