Hi Billy, Emilie
I quite agree. ALINE is often more trouble than it's worth. I've added
some text to the description of ALINE in the Users Guide. Note that
one can use PLOT/VS/LINE and specify the line color and thickness
directly with /COLOR= and /THICK= (and as Billy notes, all the
qualifiers of the PLOT command, such as /DASH specifiers)
Try this example
yes? ! Draw a plot
yes? plot/line/sym=22/i=1:5 i-3
yes? ! PUt a label inside the plot window at (3,-2) and
yes? ! draw a line from (3,2) to (2,-1)
yes? label 3,-2,-1,0,0.2 "here is the point (2,-1)"
yes? plot/vs/line/over/nolab/color=red/thick {3,2}, {-2,-1}
yes? ! Make a label outside the plot window at (3,3) and
yes? ! draw a line from (3,3) to (4,1)
yes? label 3,3,-1,0,0.2 "here is the point (4,1)"
yes? plot/vs/line/over/nolab/color=blue/thick/set {3,4}, {3,1}
yes? ppl window,off
yes? ppl plot/over

Hi Emilie -
I have stopped using ALINE as it is often flaky. You can achieve the
same effect with less bother and much more flexibility by defining your
endpoints with LET:
let xpts={4,8}; let ypts={-3,0}
plot/vs/over/nolab/line=N/dash=(...)/col= ... xpts,ypts
If you want the line to go outside the plot box:
plot/vs/over/set/....
ppl window,off
ppl plot/over

Just for info, I eventually found how to do:
use "ppl line 1,,0", cfr PPLUS guide for details.

Hi everyone,
On a time series of a variable (made with PLOT), the command PPLUS
ALINE 1,x1,y1,x2,y2" persists to draw a dashed black line instead of a
solid black line.
Does anybody know how to prevent that behaviour? I thought solid was
the default case.
Many thanks,
Emilie
