Signal analysis with labVIEW

I have a 3 axial accelerometer attached into a NI USB 6009 DAQ this signal is the seen using a DAQ ASSIST and then filtered. I am looking firstly to find the values all the way along the y axis of the accelerometer as the accelerometer moves. Is it possible to find these values from the waveform diagram?? I am also looking to add a signal to the waveform diagram the accelerates to an amplitude of 5 the is at a constant speed for a few seconds an the accelerates again to an amplitude of 3. I have only been able to find waveforms that are symmetrical. Please help me I'm really stuck and don't know what to do?

 

Thank you

What do you mean by you want to find the values along the y axis. You can add a cursor to your graph and lock it to the plot and when you move it the values for x and y will be displayed. You could also index through the array of data using a button to do the same thing.

 

To add the second set of data you just need to build an array and add it to the first array for a wave form graph and for XY graph you build an array and cluster it with the other data.

Hello

 

I am very new to LabVIEW so sorry for all the questions 🙂

 

the movement of the y plane of the accelermeter

 

Firstly you said u can add a curser to lock it to pplot when the accelerometer move how can you do this? I've been looking a cursors and I cant them out I have placed a cursor on my graphs but they were constant (just a straightline)

Inside the yellow square is wat I want to analysis.

 

How can you? index through the array of data??

 

how do you build an array to add it to the first array for a wave form graph and for XY graph you build an array and cluster it with the other data??

 

I KNOW I HAVE ALOT OF QUESTIONS I'M VERY SORRY ANY HELP WILL BE MUCHLY APPRICATED

 

THank you

If you right click on the graph you can turn on the cursor palet. For the rest of your questions I am going to have to tell you to look at examples that ship with LabVIEW. They are very helpful. Do you know how to search the examples in the Help files that ship with LabVIEW?
