I thought I should mention that the next release of Octave will use ghostscript to produce all bitmapped output. As there is some anti-aliasing involved this issue should improve.

In any event, I'm closing this report.

Octave used gnuplot for all graphical output.

When displaying the gnuplot "terminal" is set to "aqua", "x11", etc.

For bitmap output the terminal is set to "png", "jpg", "gif", etc.

For vector output the terminal is set to "postscript", "pdf", "tikz", etc.

Gnuplot has a driver for each terminal which does not rely upon the others. Thus, what you're looking to do is not consistent with how gnuplot works.

As a work around, I recommend using the MacOS X CMD+shift+4 key combination to take a snap shot of the image. That will preserve the nice anti-aliasing properties of the aqua terminal.

There has been some discussion about providing the functionality you're looking for in a future release of Octave. However, so far no one has proposed a patch.

On the Max (OS X 10.5.8), the default plots (e.g. surfc) produced with GNUTERM set to aqua are better in appearance than with GNUTERM set X11. When using "print" to save the plot as (for example) a png file, the saved image is identical to the plot that is produced with GNUTERM set X11. However, even if X11 produced the better looking plot, in my opinion the output of print should match was is being displayed

I have to believe this is already written up, but I was not able to locate the issues. I have attached aqua.png and x11.png as examples.
