[Octave-bug-tracker] [bug #50094] 2 more legend bugs

[Pantxo Diribarne]

Follow-up Comment #8, bug #50094 (project octave):

I just tested the patch on a larger screen, and it does have the expected
effect of preventing the legend from compressing the axes too much (which ends
up in a corrupted legend possition and making it disappear), so I pushed the
patch from comment #6. 
But now this is fixed for me, it uncovers another very ugly issue with the
legend item layout management: 


set(0, "defaultaxesfontsize", 12) ;
set(0, "defaultfigureunits", "normalized") ;
set(0, "defaultfigureposition", [0.682   0.702   0.25   0.25]) ;

n = 30 ;
plot(randn(4,n), "k") ;
legend(datestr(now + (1:n)), "location", "northoutside") ;
## Legend item are arranged in 2 columns 
legend boxoff
## Legend item are arranged in 30 columns
legend boxon
## Legend item are arranged in 3 columns


If I prescribe the number of columns using the "numcolumns" property then
everything look stable.
