Attached are the VIs I mentioned in the post.

Hi,
Just to double-check, have you tried to just copy and paste the "correct" digital waveform graph into the other VI and use it so both would be showing the correct vertical lines in the graphs? I can't simulate the hardware but another good step would be to double check the properties of the X-axis display formatting on the graph you are having trouble.
Right click on the digital waveform graph on the front panel > go to Display Format tab > at the bottom, select "Advanced editing mode" > make sure your other graphs have the same formating your "correct" graph which is currently set with:
Let me know if you have questions. I hope this helps!

Hi Aldo,
Yes, I have copied the graphs back and forth a few times. I checked the properties in the dialog boxes and also the properties by comparing the property nodes.
Any other ideas why this may be happening?

Hi Brian,
Assuming that you have the same properties on both graphs and it still doesn't show correctly, how about you create another copy of dig sim vi and just add the channels and visa resource controls?

Hi Aldo,
Yes, I did that when I copied the graphs back and forth between the examples from the driver and the dim sim VI I made. It doesn't work, the transitions still don't show up. I'm assuming there is something in the underlying code coming from the Tektronix driver that is changing the digital waveform and thus the graph.

Hi Brian,
I'm going to try this out on a 4000 series and look into what might be causing it. I appreciate your patience. Thanks!

Hi Aldo,
Thank you very much for your help, I appreciate it!

Hi Brian,
Have you tried running a new instance of the instrument driver for the 4000 series Tektronix? Let me know if you have already tried this.

What do you mean by "new instance"? I've opened and closed LabVIEW several times, unplugged and replugged in the scope, and basically restarted everything over the course of a couple weeks. No change. I'm also using the very latest version of the instrument driver.
