I see a lot of people on the mailing lists using the low-level "gplot" functions to do printing. I find using "plot" much easier, and I seem to recall from John's past postings that he feels this is the preferred way. I came to Octave from Matlab, so I've never read this documentation in much detail but looking at it now, it seems to give very little information about the higher level plot functions. Perhaps this explains why so many people try to do it the "hard" way (I realize that some users have good reasons for using gplot, but that should be the exception). I think the plotting documentation could use a rewrite, and I'm volunteering to submit some patches when I get some time to work on it. I want to know if there's anything else in doc/interpreter/plot.txi that is inadequately documented. One other FAQ on the help list is how to export plots. I would like to propose including the "print" function from Octave-Forge in octave. Is there a reason to not do this? Are there modifications necessary to consider including it?
