Mixed Signal Graph superposed on Waveform Chart for cursors - trouble syncing axes

[alisonkim]

Hi all,

I'm trying to use a Waveform Chart to visualize some data, and was able to add cursors thanks to Mike Manzhelly's suggestion (tl;dr superpose a Waveform Graph on the Waveform Chart, make Graph transparent, and wire Graph plot features to Chart plot features so that they read the same axes). However, I have four plots and eight total points of interest (two per plot), so I wanted to use the multi-plot cursor to minimize the number of cursors.

To do this, I replaced the Waveform Graph with a Mixed Signal Graph, but now it seems like the cursors are reading points on the Graph plot, not on the Chart plot. This is an issue because the Graph and Chart seem to display and update data differently. Attached is a screenshot for clarity: the orange and white plots are Signal 1, and purple and red are Signal 2. (The .vi uses simulated signals since I want to work on this at home without taking the DAQ drive with me.)

Am I able to connect certain property nodes together to have the cursors snap to/read the values on the orange/purple signals (those of the Waveform Chart)? I know this is possible if you use a Waveform Graph and a Waveform Chart...

Thanks in advance.

Hello, could you upload the image again? Just to see what is going on.

Oops, didn't know it had disappeared.

Hey I found this Knowledge Base article that might be helpful, have you read it already?

Yes, I've read it before. I know how to get the multiplot cursors working on a Mixed Signal Graph; I'm just unsure of how to get them to work when they're superposed on the Waveform Chart. Does my initial post make sense?

I was looking to see if I could find anything that could be done to perform what you want. Unfortunately I was not able to find a document on how to do it. I also did not find anything saying that it is not possible so it might be something that you could speak with the NI support maybe.
