Please, help us by updating the wiki. At this moment you know more
about this misdescription than anyone else.

Ok. Figured it out. The description of xlabel in jwiki is wrong - It is
not "datapoint" (based on the error message, it should be "one label per
tic position").
xlabel* c [#none ] x labels (one label per datapoint)
It works wonderfully. Thank you very much for the package!
thank you.

Thank you, Rob. I (could easily find and) read those links before
my initial ques email. I'll give you the longer story.
I had issue reconciling what I read from 2 sources:
A. From calculus.pdf, page 7 - more than 1 plot types are given to the
plot verb as its x argument:
load 'plot'
PLOT=:’stick,line’&plot
PLOT t;h
B. From the Plot/Verbs page (https://code.jsoftware.com/wiki/Plot/Verbs),
it said they should be separated by semicolons. Then, where does the comma
come from?
So, I thought the documentation was no longer up-to-date. And the
following experiments caused me further confusion:
'stick,line ; yrange _2 2 ; xtic 1p1 3' plot _2p1 2p1 ; 'sin' NB. works
'yrange _2 2 ; xtic 1p1 3 ; stick,line' plot _2p1 2p1 ; 'sin' NB. doesn't
|option not found: stick,line: signal
| signal'option not found: ',j
I read some more this morning, and did more experiments. It seems
'stick,line' belongs to the type option, and by default (only in the
beginning of x), plot assumes type's value string (and the comma is
actually optional). If we need to put them aside from the beginning of x,
we seem to have to explicitly use the type option keyword.
'yrange _2 2 ; xtic 1p1 3 ; type stick,line' plot _2p1 2p1 ; 'sin' NB.
works
This for pointing me back to the jwiki for a second look to figure this
out.
That said, I still couldn't find the equivalent of xticklabels (
https://www.mathworks.com/help/matlab/ref/xticklabels.html) in J yet.
Not yet implemented?
thank you.

Hi Maurice,
With respect to finding the documentation on the wiki, have you looked at
https://code.jsoftware.com/wiki/Plot and in particular
https://code.jsoftware.com/wiki/Plot/Options
A lot of the fine tuning of Plot seems to be done through pd. The
Development section of the plot page may also give you some useful
information.
My apologies if you have already looked at them and found them wanting,
but when you said you did not find the doc in the wiki, I just wanted to be
sure that you were aware of these.
Cheers, bob

1. plot can't handle asymptote (or "not in domain" issue) right at the
boundary in its domain?

2. I'm trying to control plot's y-scale and x-/y-tick labels. I don't
see
its doc in jwiki nor calculus.pdf. So, I tried scrolling through
Help|Studio|Showcase...|plot to see if they're possible; but still
nothing. For example, instead of a numeric value, I want to do 0, +/-
1p1, +/- 2p1, etc. Can it be done?
3. While looking for solution to #2, I stumbled upon a bug:
Help|Studio|Showcase...|isigraph. Repeatedly pressing F12 till you see
'Screen Roller' (yes, ignore Paint Demo and just hit another F12). Once
you reach this stage, Paint Demo will relaunch if you try to exit the
window. In the end, I've to kill the jqt to get out of the demo.
thanks
Maurice
