Dear all,
I'm trying to make plots with the post script device, and am trying to
increase the size of my psym=3 circular points to something that is
actually visible when saved as a .ps, but it doesn't seem to have any
effect. Can anyone see why from the below code? :
FOR i=0,a-1 DO BEGIN
!P.MULTI=0
SET_PLOT,'PS'
DEVICE,/ENCAPSULATED,FILENAME=string(filefolder)+'/Star'+str ing
(FORMAT='(I0)',ensarray[1,0,i])+'.ps',/color,bits_per_pixel= 8
loadct,13
plot,ensarray[0,*,i],ensarray[3,*,i],
$
psym=3,yrange=[min(ensarray[3,*,i]),max(ensarray
[3,*,i])],color=0,symsize=10.0,$
xtitle='HJD - 2450000',$
ytitle='dMag',$
title=' "Intrinsic Photometric Variability" of Star '+string
(FORMAT='(I0)',ensarray[1,0,i]),$
YSTYLE=8
AXIS,yaxis=1,yrange=[min(nofailarray[1,*,*]),max(nofailarray
[1,*,*])],/SAVE,ytitle='Airmass' ;Plots the right axis
oplot,nofailarray[0,*,0],nofailarray[1,*,0],psym =
3,color=120,LINESTYLE=3
ENDFOR

Doh! I looked at my code and my plot command does, indeed have
a sym=3 in the line, but it's really a hacked up version of plot and
in *that* code, it specifically swaps a 3 for an 8 where 8 is an
attempt
at really, really, small circle. Never mind... I didn't say
anything... :p

Really? Here's what I see for a plot containing 3 points (once all the
headers etc. are stripped):
10 setlinewidth L0 0.000 K 9667 6702 M Z 8178 5643 M Z 6688 4584 M Z
and the definitions of M are {moveto} and Z is {gsave currentpoint
lineto 20
setlinewidth 1 setlinecap stroke grestore}. My ps is rusty, but it
looks like it's just drawing a line from the current point to the
current point, with rounded edges at each end of the line - so a real
dot.
-Jeremy.
