I have to say that R documentation is more pleasant/clear than Octave/gnuplot. My understanding is that (unlike for R) we do not try to do anything for Octave plotting, so everything is "default". Plotting commands in Octave use either gnuplot or OpenGL, but it seems that in our setup only gnuplot is available. How extractly it is used I don't know, but my guess is that Octave creates some input file and then passes it to "gnuplot" and you have an option to change the name of the called binary and supply some options to it. For whatever reason, default options result in just ASCII plot in SageMathCell and SageNB. When I try to add explicit commands for saving in a particular format I am just getting the same ASCII plot one more time and some warnings. Starting Octave from a local terminal allows me to open plots in a new window, while saving files works but still shows warning about missing things. It would be nice if someone who knows Octave and gnuplot figured out what do we need to do to get some plots and no warnings - I am stopping for now.
