Both things. Every visual function should have a %!demo so we can catch differences with the dump_plot_demos script. But I mostly wanted a picture in the PDF documentation which is the second thing. It's cool that Octave-Forge has already been hooked up that way, but I was thinking of just one, or maybe two, pictures per function that were for documentation purposes.

Do you mean that each plotting function should have at least one demo or that demos (all or part of) should appear in the html/pdf versions of the manual. I agree with the former, and the latter seams to have been implemented in the documentation generated in octave-forge. See e.g. http://octave.sourceforge.net/octave/function/contourf.html

It would be very helpful if every plot/image function had at least one accompanying image to demonstrate what the function actually does.

In English, we say "A picture is worth a thousand words". And it is true that it is often very difficult to document in text the output of a function, but quite easy to show it.

As an example, the text for the jet colormap is.

I'm not sure what that would look like, but the image from

is quite clear.
