[Octave-bug-tracker] [bug #40686] Incorrect colorbar size after "axis tight" or "axis equal"

[Dan Sebald]

Follow-up Comment #13, bug #40686 (project octave):

Oh, no actual gnuplot colorbox.  That sort of rings a bell.

Your logic seems correct, other than "equal" and "square" not being the same
thing in gnuplot.  I think "equal" refers to the units being equal on all
dimensions, whereas "square" means to make the plot square.  I see the use of
"equal", but you are right that there is no counterpart, i.e., "noequal".

An alternative to where you placed "nosquare", is to put the counter-part
where the "equal" is.  That is, rather than a strategy of undoing what's been
done, set the appropriate setting at the point where that property is set. 
Attached is an example, but I don't think it is 100% correct because nd == 3
restricts this to 3D plots, whereas it could be the successive plot is 2D and
hence the "equal" would still not be undone.

Anyway, look into that; you're on the right path.  There is a "equal/noequal"
and a "square/nosquare" to account for if both those settings are used.
