I have two serial devices that I am controlling. One device will be acquiring data from x number of transducers. The other device will cycle through y number of channels and acquire data. I have put graphs of the data from each device in separate tab controls. I have a boolean that controls which tab control is visible. However, the graph in the tab control that is not visible still partially appears. I am using LabVIEW version 6.0.2. Anybody know of any fixes.
