[Octave-bug-tracker] [bug #56798] semilogy - "omitting non-positive data in log plot" and empty plot with all positive data

[Andrea Baldoni]

Follow-up Comment #3, bug #56798 (project octave):


[comment #2 comment #2:]
> The message you are seeing is just a warning (a puzzling one but still). The
positive data should still be plotted.

Well, I understand the warning as 0 is not positve, however,
the plot is completely empty, so there's definitely something
wrong. By the way, curiously, adding 0^-14 instead of 10^-14
(or 0^-1, or 0^-2 but not adding just 0 or 0^1 or 0^2!!!!) suppress the
warning. Plot keeps to be empty.

> I am assuming you are using the qt graphics toolkit for plotting. What does
gnuplot do?

I was already using gnuplot, qt hangs with empty window.
I added the "close all" that wasn't in my code, but as
there were not other windows anyway, it didn't change.
