Hello everyone. I am new to LabView and have no basics of electrical engineering. I have to create a VI where graphs of force/displacement and torque displacement will be displayed. Basically I have 2 LVDTs that will provide the position, 1 load cell and 1 torque cell. Do you think it's possible ? This will hopefully be used by doctors who will only need the graph and whitout any knowledge of LabView. Also the VI has to be universal that is, applicable to all patients.
Thanks in advance and Im so sorry if these are dumb questions

You might find it useful to draw out what you want your program to look like before you start writing too much code.
Once you have a clear idea of which buttons you want where, what should happen when you press them, whether you need to save and load data and so on, it can be much easier to work out how to code it.
Even more usefully, it provides a combination of to-do and checklist for your work.

Let's quickly go back to the "electrical engineering" part. At this point you should look at the hardware and see what kind of signals these put out (and possibly require). For example a simple load cell typically contains a bridge circuit, which requires a precise excitation voltage. There are chips that can simplify the connection (example) but NI also has special modules for bridge measurements (start reading here). Even simple voltage measurements might require bias resistors and such, so read the documentation.
So clearly, the design of your interface requires quite a bit of electrical engineering and programming in LabVIEW is maybe the easiest part of the problem. Do you have local resources that can help you? What kind of hardware are you planning to use?
