The most commonly used functionality of gnuplot is supported directly by the

To apply an extra style to I<all> the curves that lack an explicit C<--style>,
pass in C<--styleall extrastyle>. In the most common case, the extra style is
C<with something>. To support this more simply, you can pass in C<--with
something> instead of C<--styleall 'with something'>. C<--styleall> and

overrides the global C<--styleall> or C<--with> setting.
