[Octave-bug-tracker] [bug #48616] Matlab compatibility for semilogx() and xlim([0 uplim])

[Ben Abbott]

Follow-up Comment #5, bug #48616 (project octave):

I've tried both the default branch and the stable branch. In each case, the
script (test_log.m which is attached) produces the output below. 


>> graphics_toolkit qt
>> test_lot
error: 'test_lot' undefined near line 1 column 1

I do not see the warning from libinterp/corefcn/gl-render.cc.


"opengl_renderer: data values greater than float capacity.  (1) Scale data, or
(2) Use gnuplot"


I've attached a png of the figure I get using the qt graphics toolkit.

@Franz, when you see the warning from gl-render.cc are you using the fltk, or
qt graphics toolkit? You can check by entering "graphics_toolkit" at Octave's
prompt (I don't encounter the error from gl-render.cc for fltk either).
