Lots of channels to manage

Hello Everyone,

 

I have written a VI that will allow me to collect data from 200 different channels across 25 different wireless sensor nodes.

 

I started a second vi that will access the files that I am writing the data to in order to generate graphs.

What I want this VI to do?

- First, i would like to select the channels that i would like to view on my graph.

- Next, i want to access the files and build a new array with the parameters that i have selected.

(my abilities are good to this point)

- When it comes to putting these parameters to an XY Graph, I'm lost.  I'm not sure how to do it because the number of channels selected will vary each time i want to run a different graph.  I have attached the typical way that i generate a XY Graph just showing four channels and i'm not sure how to build a different sized array for the graph each time i select an additional parameter.

lockesmith,

 

This code snippet shows how to choose the number of plots you want in your XY graph. Maybe this will get you going in the right direction.
