Optional left arguments specify various characteristics the user
requires, but
I can never remember them, and typically run the plot lap and crib the
scripts
accompanying the various samplers.
Evidently, 'ylog 1' plot 1 2 4 shows a straight line through (0,log 1)
(1, log2) (2, log4)
whereas 'ylog 2' plot 1 2 4 shows a straight line through (0,log 10)
(1, log100) (2, log10000)
and 'ylog 3' plot 1 2 4 shows a straight line through (0,log
1e10) (1, log 1e100) (2, unlabelled)
... presumably the unlabelled value would be 1e10000, but I don't
understand the y scaling, without
looking it up, and it's late!

what is ylog ? 'ylog 1' appears to be in the same class as 'hello

You probably know this, but anyway:
It's OK - well, fails gracefully - in JQt 807 under Windows 10.
the plot window opens, but with an error box saying:
[ J Plot X ]
[ (I) |NaN error: gettplog ]
[ [ OK ] ]
while on my iPad, iOS 12.4.5, (typing what I see there)
'ylog 1' plot 1 0 2
|NaN error: gettplog

'ylog 1' plot 1 0 2

Dear list,
load 'plot'
'ylog 1' plot 1 0 2
leads to an immediate crash of the J session for me (now win 10,
jqt901). I know that log 0 is NaN, but still...
Thanks
