distort chart curve

[Qia.sky]

Someone can tell me why this could happen?

When I minimize the windows which contain Chart curve, and of course the Chart is updating. But When I show that windows again, the chart curve seems being distorted.

How could this happen? someone can tell me why and how to fix it.

Thanks very much

It could be a LAbVIEW bug, but I have never seen this. Do you have an simple example program to share that we can try to reproduce the problem? What is your LabVIEW version.

Many times, things like that could be caused by a bug in the driver for your video card. What is the model of your video card?  Have you tried finding an updated driver?
