works now, thanks! Op di 12 sep 2023 om 09:47 schreef Tomio Arisaka tomio-arisaka@users.sourceforge.net: I guess your Maxima fails to search $PATH for gnuplot. So I think you should let Maxima know the path to gnuplot. For example: (%i1) system ("which gnuplot") $/opt/local/bin/gnuplot (%i2) gnuplot_command ;(%o2) gnuplot(%i3) gnuplot_command : "/opt/local/bin/gnuplot" ;(%o3) /opt/local/bin/gnuplot(%i4) plot2d (4x^2-8x+2, [x,-1,5]) ;(%o4) false [bugs:#4183] https://sourceforge.net/p/maxima/bugs/4183/...

no it doesn't, but now gives another error: plot2d(4x^2-8x+2, [x,-1,5]); Maxima encountered a Lisp error: Couldn't execute "gnuplot": No such file or directory Automatically continuing. To enable the Lisp debugger set debugger-hook to nil. Op ma 11 sep 2023 om 21:55 schreef "Gunter Königsmann" peterpall@users.sourceforge.net: does plot3d (without the wx) work?
