Yes, I would like to take a snapshot of the Contour plot and put it
into a movie. However, it is not working, there is just a black
screen. This is the main part of my 'Readdata':
c1=contour(data,x,y,rgb_table=33,/fill,c_value=userlevels,$
Position=[0.1, 0.15, 0.9, 0.90],c_color=indgen(levels),$
title=['Density at t ='+string(time)],,/overplot)
Except of the overplot command, there is no specification how to
handle the window.
If I use the following command, I can see the title of my plot in a
movie, but no contour plot:
loadct, 1
set_plot,'z',/copy
device, set_resolution=framedims, set_pixel_depth=24, decomposed=0
for i=0,nframes-1 do begin
filename ='DATA_000' +strtrim(i,2)+'.tab'
readdata,filename
xyouts, 0.5, 0.9, 'IDL TITLE', align=0.5, charsize=2, /normal
timestamp = video.put(stream, tvrd(true=1))
endfor
