Hello all
I have a plotting routine that take 6 different files and plots them in an multigraphic window. Each plot have at least 10^6 points.
So when I try to do
p06.save, 'My Plot.emf'
the program never ends and I never have the file saved as I want to.
I was wondering if this is because the large amount of point in the plots, or because it is a multigraphic plot and I am only calling the save command to the last plot generated in the window.
Also , just to plot takes a long time, is this normal?
Thank you
Luz Maria

Certainly, you can test this, outside of your current, mulitgraphic workflow to try to answer the question:
p= PLOT(RANDOMN(1L, 1000000), layout=[1, 2, 1])
p2= PLOT(RANDOMN(1L, 1000000), layout=[1, 2, 2], /CURR)
tic
;p.symbol=4
p.save, 'test.png'
toc
For me, this took 60 seconds. If I actually plot the points (by adding p.symbol=4), then it takes 121 seconds.
You can then try to add plots to see how the time changes:
You can then add a second plot:
p= PLOT(RANDOMN(1L, 1000000), layout=[1, 2, 1])
p2= PLOT(RANDOMN(1L, 1000000), layout=[1, 2, 2], /CURR)
tic
;p.symbol=4 & p2.symbol =4
p.save, 'test.png'
toc
Without plotting the individual points, it takes 55 seconds (?!); plotting each point, it takes 175 seconds.
These simple tests will allow you to figure out where the problem may be, and help answer your questions.

Hello Phillip
Thank yo for the recomendation, I tried and it looks like for each plot I added (using symbols) it was taking abour 100 seconds. so it kind of agrees with your little experiment.
I was alsoo trying to dave it as EMF instead of PNG, and I guess that was causing a lot of the delay .
regards,
Luz Maria
