[Octave-bug-tracker] [bug #39449] log axis minorticks incorrect if axis limit exceeds 8 orders of magnitude

[Rik]

Update of bug #39449 (project octave):

                Category:                Plotting => Plotting with OpenGL   
                  Status:                    None => Confirmed              
                 Summary: xminorticks for a semilogx plot incorrectly
displayed => log axis minorticks incorrect if axis limit exceeds 8 orders of
magnitude

Follow-up Comment #2:

Re-titling this bug to be clear about the problem.  Simple sample code to
reproduce the problem is:


x = 10.^[0:8];
y = 1:numel (x);
semilogx (x, y);
set (gca, "xminorgrid", "on");


The displayed plot will not have a grid from 1e0 to 1e1, but will from 1e1 to
1e2, won't from 1e2 to 1e3, and will from 1e3 to 1e4, etc.

The problem occurs whenever there are greater than 8 orders of magnituted for
the axis limit.  In the above example, xlim ([1,1e7]), causes the axis to
display correctly.

This is only a problem with the FLTK backend.
