Traces Disappear When Changing Time Axis

I am using a graph to display data, which has been working great for quite some time. However, I've ran into a problem where the graph displays fine, as in Caputure1.png, but as I change the ScaleFrom parameter past a certain time (in this case, since 6:45 am this morning) the entire trace disappears, as in Capture2.png. There should be Persist data long past that point in time, as the program has been running continuously for days (Persist = 1000000). In my past experience, even if the ScaleFrom parameter goes farther back than the earliest Persist point, the graph still displays all the existing Persist points. 

Any ideas why, in this particular case, the traces are just disappearing?
