write plots alternately to two postscripts files [message #73009] Tue, 19 October 2010 08:31

The problem sounds easy, but I do not know where to find the solution.
I want to write a program which should create two different postscript files, each having 100+ pages.
However I don't want to open, create and close them one after another.
It should work like this:

Read and process a chunk of data.
Add a plot to file 1
Add a plot to file 2
Read and process new chunk of data
add a plot to file 1
Add a plot to file 2
and so on

As the processed data is really large it is not possible to keep it all in memory. So first finish file1 and then create file2 is not an option.

Is there any chance to switsch between to output files?
Any help is appreciated!
Simon
