Line plots rendition in (default) solidline style depends on how big the numbers are... Does not happen when linestyle is point-like. Does not happen with gnuplot backend. Does happen with qt and fltk. Try this:

>> version

ans = 6.1.0

>> graphics_toolkit

ans = fltk

>> tn=now:1/864:now+1;   % make some date related (large) numbers
>> plot(tn,'.')          % ok (linear splope, as expected)
>> plot(tn)              % Not ok at all !!!  (broken  line)
>> plot(tn-tn(1))        % Ok again but with smaller number

Happens in:
Windows 6.1.0
Gnu/Linux 4.2.0
