Writing to pgfAxis environment from other function than drawAxes()

[blubbafett]

In drawAxes() this is written:

% Store a pointer to the current pgfplotsEnvironment axis environment
% as plot objects further below in the hierarchy might want to append
% something.
% One example is the required 'ybar stacked' option for stacked bar
% plots.
m2t.currentHandles.pgfAxis = env;

which makes me believe that I can update the content (m2t.currentHandles.pgfAxis.options) from another nested function before the content is printed to the actual file.

Thus, if I in f.ex drawLine() want to append something, I could write:

pgfAxis = m2t.currentHandles.pgfAxis.options;
newOpts = blablabla;
pgfAxis = appendOptions( pgfAxis, newOpts );
m2t.currentHandles.pgfAxis.options = pgfAxis;

But after trying for a while now it's obvious I'm missing out on something; the options are indeed updated in the struct, but not printed to the file.

So the question is; what am I missing here?

Just made a hack in the savToFile() function for testing;

m2t.content.children{1}.options = appendOptions( m2t.content.children{1}.options, m2t.currentHandles.pgfAxis.options );

Suggestions for improvement are welcome. :)

I don't understand the issue -- you wanna append something to the options of the current enviroment and it doesn't work?

I wanted to write some options under

\begin{axis}[%
*bla,
*bla,
*bla,
-new_bla,
-new_bla]coordinates{xxxxxxx}
\end{axis}

where *bla is written from the drawAxes() function and -new_bla from any other function. I.e. if I want to add the z-limits for a 3D plot, they have to be placed as options in the axis environment, and not as options in the surf environment (\addplot3[surf]) . However, I when in drawSurface() I couldn't find a way to directly access the axis environment instead of the surface which I was plotting; hence the hack I mentioned. But it works as it is now, but as mentioned, not the cleanest solution. Should be easy to fix once I understand how to append the new options directly to the axis environment (env.options in drawAxes()).

Ah okay. Well, that had worked before but broke at some point such that, for example, stacked bar plots (which need 'ybar stacked' in the containing axes environment) didn't work anymore.
I've tried to fix this now by providing m2t.currentAxesContainer of which you could access m2t.currentAxesContainer.options to append something there. Closing this for now, please reopen if necessary.
