I have the following code to plot some data (~25000 points) using the
PLOT() function:
tic
po = plot(fo, ro, $
xrange=xrange, $
yrange=[-0.005,0.025], $
xticklen = ticklen, $
yticklen = ticklen, $
xtickfont_size = 9, $
ytickfont_size = 9, $
color = 'red', $
thick = 1 ) ; <<<---****
pn = plot(fn, rn, $
color='green', $
symbol = 'diamond', $
/overplot)
pz = plot(po.xrange,[0,0], $
linestyle='dashed', $
/overplot)
pz.order, /send_to_back
toc
When I run this I get the plot and the following output from toc:
% Time elapsed: 1.1067200 seconds.
I then changed *ONLY* the value of thick to "thick = 2", recompiled the
procedure, and ran it. I got the following:
% Time elapsed: 25.625711 seconds.
Am I doing something stupidly wrong here, or is this a known bug?

p.s. The first time this happened I thought my computer had karked it so
I did the ctrl-C dealy after about 10-15 seconds and got the following:
^C^C^C^C^C^C^C^C
