Overview: This VI uses a loop structure to create a linear graph with random "noise".

Description:

This VI uses a loop structure to create a linear graph with random "noise". This is done by adding the random number generator VI to a linearly increasing y value. Once the graph is created, a linear fit VI will fit the best curve to it display it on the front panel.

Requirements: LabVIEW 2012 (or compatible), Hardware: none.

Steps to Implement or Execute Code:

1. Run the VI.
2. The results are on the graphs.

First, I'm a novice in LabVIEW programming. I opened this vi, but it's unclear to me how I input the waveform data. I think this is the vi that will fit perfectly into my program. Could anyone help?
