Hi, I am having several problems with my graph. Basically whenever I move the front panel around or shake it, the data does not seem to be logged and it screws up the graph. Secondly, whenever my buffer fills up, 50% of the time, there is this line that appears from the end of the graph to the beginning for a split second. I dont understand why it would only happen sometimes though, because many times the buffer fills up but this does not happen. If anyone had this problem before and knows a good way to fix it, it would be appreciated. I tried doing defer and undefer front panel updates but this did not help my graph. My CPU usage is pretty high as well.

I don't know the details of the Galil motion card but it sounds like you might be controlling it from the user interface thread. When you hold the mouse down on a window border in Windows, the UI thread is unavailable for a period of time and the DLL call will just block. If you are controlling the Galil with a DLL, see if the DLL is set to run in the user interface thread (it will be orange.) This is the default; LabView assumes your DLL is not thread-safe unless you specifically identify that it is. If the DLL is thread-safe, you can just change the call setup to let it run in any thread.

The strange thing is, I used the same buffer elsewhere but the error didn't happen.

Raven, I am rotating the data though. And I don't want to use the NaN solution, its not really solving the problem, but working around it.
