[Octave-bug-tracker] [bug #43282] annotation function missing

[Pantxo Diribarne]

Follow-up Comment #12, bug #43282 (project octave):

@Rik: I ran the attached script with and without the patch (updated also to
avoid findall function an a few quirks). It basically creates multiple axes on
the same figure. The results are the following:


Without patch
1 axes:         0.01 s
2 axes:         0.02 s
4 axes:         0.03 s
8 axes:         0.07 s
16 axes:        0.14 s
32 axes:        0.27 s   

With patch
1 axes:         0.01 s
2 axes:         0.02 s
4 axes:         0.04 s
8 axes:         0.09 s
16 axes:        0.18 s
32 axes:        0.40 s


There is indeed a performance hit for a large number of axes in a figure. In
the mean time 30 axes in a figure is quite large. 

I also noticed that if annotation function is called first in a figure, it
becomes the currentaxes which should not happen. I updated annotation.m to
take this into account. 
 
@Michael: depends on when feature freeze is declared. Is there a proposed
date? I have no time now to cleanup the new patch but I may be able to post it
in the beginning of next week. Nevertheless if John wants to work on
integration, it will probably look like (or be) the attached
add_annotation2.patch.
