Hi, I use DDE for real time graphing in Origin 7 PRO. Our Data aquisition system sends data at regular time intervals through DDE to Origin in Real Time. We recently had a trial run and saw that the CPU usage was very less for the first few minutes (< 10%) and then it shot up to 50-70%.I tried changing various parameters, but it still showed the same results. What could be the reason for this behaviour-CPU usage increasing with time? Is it because of the size of the datasheet which also increases with time? Is there a way to overcome this problem?
Thanks, Deepak Samuel. |
