Graphic option
user_preamble
Default value: ""
(empty string)
Expert Gnuplot users can make use of this option to fine tune Gnuplot's
behaviour by writing settings to be sent before the plot
or splot
command.
The value of this option must be a string or a list of strings (one per line).
Since this is a global graphics option, its position in the scene description does not matter.
Example:
The dumb terminal is not supported by package draw
,
but it is possible to set it by making use of option user_preamble
,
