You should try to use the REFRESH method: "The Refresh method enables
and disables the refresh (drawing) of the graphics window. This method
is useful if you are doing a large number of graphics updates and you
do not want to see the intermediate steps."

Compare these two versions:

;;; Slow version
b = barplot(/test)
for i=0, 20 do begin
color = [randomu(seed,1)*255, randomu(seed,1)*255, randomu(seed,
1)*255]
!null = barplot(/test, /overplot, transparency=50, color=color,
fill_color=color)
endfor

;;; Faster version
b = barplot(/test)
b.refresh, /DISABLE ; Disable re-draws.
for i=0, 20 do begin
color = [randomu(seed,1)*255, randomu(seed,1)*255, randomu(seed,
1)*255]
!null = barplot(/test, /overplot, transparency=50, color=color,
fill_color=color)
endfor
b.refresh ; Re-enable drawing and show the results.
