[Gnuplot-info] logscale and 0 values

[Sam S. <sd...@gn...>]

when there is a row with a 0 in my dataset and I want to use logscale, I
get an error: "range must be greater than 0 for log scale".
I can specify the range myself, of course, but it would be better if the
above were a warning instead and the range were set by the smallest non0
 entry.

Doesn't reproduce here, in a quick experiment:

No warning, no error nothing.

Oh, FYI, that's with version 4.2 on Windows.
