[Octave-bug-tracker] [bug #34158] axis with x_min>x_max

[Matthias Jüschke]

Follow-up Comment #3, bug #34158 (project octave):

For x- y- zlim.m there is a similar effect. As I found in 
/usr/share/octave/3.4.0/m/plot/private/__axes_limits__.m
the last case of the if-block

      else
        set (h, fcn, arg(:));
      endif

should be replaced by something like

      else
        if arg(1)>=arg(2)
          error('Axis limits must be increasing.')
        else
          set (h, fcn, arg(:));
        endif
      endif

In matlab, you can set a value to Inf, if it is the second, the axis is set to
arg(1)+1.
