I am having a problem with an XY graph which is displaying data that are continuously collected from 3 AI channels. Every time the graph updates whole portions of the plots disappear and then reappear during subsequent updates. The actual data are still there (can be probed with a cursor) but the graph display doesn't show it. I attached two images showing the problem. In 1.bmp all three plots have the exact same # of data points but the green and red plots are not displaying toward the end. In 2.bmp all plots have several areas that have blanked out.
So far I have tried:
Changing priority in task manager to high: did not help
Slowing down graph updates: did not help. the problem definitely follows the graph update frequency though. If the graph updates every .5 seconds the problem only occurs every .5 seconds.
Turning on antialiasing: fixed the problem but computer slows to a crawl. (integrated graphics)
Switching computers : fixed the problem.
Minimizing and Maximizing the window : did not help.
Computer specs where problem is occuring:
I3 2100 ~3ghz
3gb ram
integrated graphics
windows xp
labview runtime 2012
Next I will try a computer with dedicated graphics card. Just wondering if anyone else has experienced this problem. Thanks!
