[Mike Miller]

Update of bug #48509 (project octave):

                  Status:            Works For Me => Invalid

Follow-up Comment #5:

Ok. I think you may be misunderstanding how plotting and the hold function
work. You may want to ask for clarification on the help mailing list (see
http://www.octave.org/support).

You say that you plot cos(x) vs x, the plot shows correctly. Then you close
the plot window. Then you run "hold on'. Yes, that is supposed to create a new
figure window. When you close the first figure window, whatever you plotted in
it has now been lost. If you return to the Octave command prompt _without_
closing the figure window, then you should be able to enter additional
commands, including "hold on" and subsequent plot commands, which will affect
the existing plot. However, as soon as you call the "close" function or click
to close the plot window, the contents are lost.

Also version 3.6.4 is quite old. Are you using that version because you want
to use Octave with Visual Studio?

Anyway, I'm closing this bug report since things seem to be working correctly.
It's not that the "hold on" function is clearing the plot, it's that you
closing the plot is clearing it.
