[Nicholas Jankowski]

Update of bug #62873 (project octave):

                Severity:              3 - Normal => 2 - Minor              
                Priority:              5 - Normal => 3 - Low                
              Item Group:                    None => Other

Follow-up Comment #1:

comparing results from octave and matlab using a test case:


[x,y,z] = peaks;
[C,h] = contour(x,y,z,[-8:2:8]);
clabel(C,h);


produces the attached image comparing Octave 7.2.0 and Matlab 2022a.

Octave's is definitely less legible. note that matlab breaks the lines behind
the numbers, and the font size defaults larger. the brighter colormap probably
helps contrast a bit as well. 

Also, note that without specifying the levels with the [-8:2:8], octave did
not choose integer spaced levels making the labels much longer text strings.
