[Octave-bug-tracker] [bug #44096] plotboxaspectratio wrong value for "axis equal"

[Avinoam Kalma]

Follow-up Comment #2, bug #44096 (project octave):

You are right.
Using Matlab R2010a, I get


plot (1:10)
axis equal
get (gca,'plotboxaspectratio')
   520.8000  410.7600   91.2800


which is not [3 4 4], neither [5 4 4].
Debugging Matlab code, shows in axis.m that plotboxaspectratio is computed in
the following way:

dx = diff(get(gca,'xlim'));
dy = diff(get(gca,'ylim'));
dz = diff(get(gca,'zlim'));

set(gca,'Units','Pixels');
a = get (gca,'position');

b = [a(3)  a(4) dz*min(a(3),a(4))/min(dx,dy)]
b =
  520.8000  410.7600   91.2800


and plotboxaspectratio is set bo b.
If you run this in octave you will get a different answer:


b =
    434.000   342.300    34.230


because dx,dy,dz are different.

What do you recommend to do now?
