RealTime Update rate of UI CWGraph - critical

[Idity]

I am working with your UI graph in its very simple XY (chartStrip) 2D mode. No zooming using, windowless etc.

I am trying to display 10 graphs with 8 plots each, and history of 10,000 samples.

My raw data rate is one data per plot each second.

My problem describes as follow:

When I run my program the update rate is well (1 dot per second on each plot) but after 10 minutes the update rate of the graphs becomes slower and slower (1 dot per 3 seconds).
When I clear the graphs data it returns to the initial update rate.

Do you have any suggestion what is my problem and how can I solve it???

I am trying to handle it for a long time and also sent your support an E-mail, so please answer me as soon as possible.


Thanks a lot

Idity,

Could you submit a sample project I could run in house? This way I can examine your code and hopefully try to reproduce the same behavior.

Thanks!

I have identified the same problem in my project. See my posting 23 sept. "CWGraph increases CPU load as more data is added". NI have been contacted on this issue and I am awaiting an answer from them.
