This is come from octave bug tracker for gnuplot graphics_toolkit
https://savannah.gnu.org/bugs/?49003

gnuplot> set term qt
Terminal type set to 'qt'
Options are '0 font "Sans,9"'
gnuplot> set termoption dashed
gnuplot> set term tikz
Terminal type set to 'tikz'
Options are 'latex nopreamble color nostandalone nogparrows notikzarrows nogppoints picenvironment nooriginreset bitmap rgbimage noclip notightboundingbox noexternalimages '
gnuplot> set termoption dashed
                              ^
         warning: unknown option `dashed'.

As far as I investigated, only tikz ouputs the warning.
Of cource, gnuplot 4.6, set termoption dashed does not give warning on tikz terminal.

Karl
Thank for the pointer.

Discussion in the ticket #1828 implies that it is better not to exepect the re-implementation of "termoption dased" to the tikz terminals.
Is my understading correct?

[Ethan Merritt]

That is correct. "set termoption dashed" no longer has any effect.

There is some disagreement about whether the program should issue a warning or ignore the command in silence.

Thank you for the reply. I understand the situation. OK I will close this ticket.
