Use the magic line to control the gnuplot plugin behavior.
By default, we use the eps output, that's why it is black and white.
Put the following line to the first line of your repl or script, figures will be colorful.
% -output png
And I have improved SVG support in GNU TeXmacs, I will set the default format to SVG.
For GNU TeXmacs 2.1.1 (has not been released yet), the magic line mentioned above is not needed.

Dear all,
Figures generated by gnuplot is colorful, while within texmacs they entail only black and white.
It becomes annoying when people want to draw multiple functions in the same figure, especially multiple surfaces.
Is it possible to recover it?
Sincerely,
Hammer Hu
