As Jordi pointed out this feature request is already under way in the development of the OpenGL backend(s). Thus, depending upon the context this is either fixed or in progress.

Thus, if there are no objections, I suggest this item be closed. I'm assigning this to myself so that I don't forget about it.

I did not realise you were trying to move away from using gnuplot, I'll bear that in mind and post individual issues as they arise.

Thanks for the debug work-around. That will at least let me tweek in any loose ends that I can not resolve directly.

Thx

We disagree. gnuplot has many limitations, particularly for 3d
plotting, and it's very difficult to control it from Octave. We have
been trying to move away from gnuplot for a long time, and I'm hoping
that for 3.6, gnuplot will no longer be the default plotting engine.

If you want gnuplot, then keep using gnuplot. Octave is not gnuplot,
and you cannot send direct gnuplot commands from Octave anymore, at
least not easily, and this is intentional.

Here's a trick that will let you see the gnuplot commands that Octave
sends, which you can then manually edit and run in gnuplot. This is a
debug feature and is liable to be broken at any time:

now debug.gp contains the gnuplot commands for you to edit and run
without Octave.

That being said, it would be more useful if instead you told us which
plotting features you're missing so we can implement them, with and
without gnuplot.

I am a great fan of gnuplot and use it a lot. It is a great choice as the plotting back-end for octave.

Hwvr, I am continually frustrated by the lack of control (and hence plotting features) accessible from octave.

Accepting there are certain limitations if alternative back-ends are used concurrently, it would be very useful if there was some sort of mechanism for passing gnuplot commands directly for where there is no direct control via octave.

Better documentation would probably also help find some things it seems are impossible but may be.
