Posted - 07 May 2006 : 02:55:39 Hi, I wanted to know is there's a way I can control the number of values saved as history of strip chart's process vars. I have a strip chart in my application with several vars that get a lot of values per second, and after a short time I get "java.lang.OutOfMemoryError: Java heap space" exception. I think it might have something to do with the values saved as history. Thanks, Galit.

Exactly how many variables are you talking about?
Exactly how many updates per second of the RTProcessVar variables?
Exactly how many updates before the stack error occurs?
What is the update rate of the display ?
Exactly what is the extent of the time axis you are using?
How much memory does your system have ?
Can you reproduce the problem by making simple changes to any of our example programs, ScrollApplication1 for example ?
