I'am not so sure that DG is faster than NG !
alx.

IDL> p = randomn(rien, 1024L*1024)
IDL> t=systime(1) & plot, p, PSYM=3 & print,'DG elaps:',systime(1)-t
DG elaps: 16.110000
IDL> t=systime(1) & q=plot(p, LINESTYLE=6, SYMBOL='dot') & print,'DG
elaps:',systime(1)-t
% Loaded DLM: XML.
NG elaps: 11.740000
