I am trying to take a waveform chart and have it plot the exact same information on a waveform chart in a subvi. Right now the waveform chart is getting the information from a DAQmx Global Channel and the information is being displayed on the waveform chart. I want to pass this information to a subvi along with information from a string that the user will have typed information into. I only want the subvi to run the case structure if the Boolean on the main vi it true. The purpose of the subvi is to automatically save (eventually print) the front panel of the subvi as a jpeg/bmp/png. I've attached the vi file for the sub vi and an image of the main vi. I can't give the file out for the main vi. Image 1 is the front panel of the main vi which is the same information that I want to transfer to the subvi. Image 2 is the block diagram of the main vi with the information being passed to the subvi. The subvi I have the waveform chart and the string input from the main vi as well as a Boolean operator to turn on the control to save the front panel as a jpeg. Right now I can't get any information to transfer to the waveform chart in the subvi and what I am trying to get happen is I run a certain sample and when I go to stop my main vi the waveform chart will have copied the same data to the subvi and the subvi will save the front panel of the subvi as a jpeg. I'm sure I'm missing something extremely obvious but I haven't been able to figure it out using the forum and the NI help. Any help is appreciated, thank you.

I uh... I made a video about it. I hope that you don't mind. I stumble my words a little bit, you know, refer to outputs as inputs, confuse left from right and laugh unnecessarily. But I think it does the job. Let me know how you get on.

Passing a Waveform Chart from main Vi to Subvi

Solved!

So, you made a solution and decided to make it private. Sometimes the comedy in this forum just writes it's self
