I committed the second part of the patch, to add a new -ddumb device to print.  I didn't change the creation of images for the documentation because I think it makes more sense to say that the image can't be displayed then to try and render complex images with ASCII art.

The changeset is here:  This will be a part of the Octave 5.0 release scheduled for release early in 2019.

Marking as Done and closing report.

this patchset adds a "-ddumb" device to print for gnuplot.  The device prints
the plot as ascii art.  "dumb" is already supported as device in drawnow.  The
main use case for "dumb" in print right now would be info manual output. 
Currently the plots in the documentation are only included in a graphical
version which is not supported by terminal info viewers.  With this patch the
documentation could include an ascii art version of the plots.

One problem remains: There should be a way to specify the size of the plot in
characters.  Right now the patch adds a fixed size (drawnow as default uses
COLUMNS/ROWS value for the existing terminal).  Using -S to pass the
information seems like a bad idea because -S usually expects size in pixel.

The second part of the patch changes some of the doc plot generators to use "-
ddumb".  But the generated plots are a bit too large right now (72x24) and can
cause issues in Emacs info mode and the standalone info viewer.



(Note: upload size limit is set to 16384 kB, after insertion of the required escape characters.)
