Find area between waveform and time axe

[dsasorin]

Hi.

I aquired a signal at 1ms rate. I saved to a .lvm file, and now i want to compute area between waveform and time axe. So, it is a classic integrale.

So i create a separate .vi with a read measurement module, but i don't know which is the right module for integration, in this case. I tried all the integrate modules to find the area, but no good results.

PS: I also want to display this area, to hasurate somehow, but this is secondary.

Any idea ?

For the first part we should look at your code and data.

For the second use the "Fill to" option available for the plot which will fill in the area you specify.

The integral of a waveform should just be the sum of the subset of Ypoints (from T1 to T2) times dt.  I assumed the Time axis is at a Y =0.
