Matlab no longer supports erasemode, and Octave won't either. Closing report.

Confirmed.

I'm afraid Octave supports getting/setting the property value only. There is no actual graphic rendering code that takes into account the value of erasemode. I don't think too many people use this feature, since you were the first to report it, so it probably won't be fixed until someone takes an active interest in it. The file to start with in octave is probably gl-render.cc.

Hello,

I wrote an quick&dirty code to illustrate:

The command
set(h,'erasemode','none');
should do the following (according to Matlab doc):

none — Do not erase the line when it is moved or destroyed. While the object is still visible on the screen after erasing with EraseMode none, you cannot print it, because MATLAB stores no information about its former location.

However, the former lines are not visible on the screen after new coordinates are set.

Sorry in case I did a mistake.
