Using the Octave kernel with Jupyter notebook does not plot any figures.

A cel containing the simple code : plot([1,2],[3,4])

returns the error:

# Error message

Inline plot failed, consider trying another graphics toolkit

error: **gnuplot_drawnow**: the gnuplot terminal, “postscript”, is not available

error: called from

_make_figures>safe_print at line 125 column 7

_make_figures at line 49 column 13

Since gnuplot is called in Octave, is the call corrupt? Or settings not correct?
