I have a vi set up to build two 1d arrays of data more or less on a timer, with 10 data points each. I then use those arrays to create an XY graph. What I can't figure out how to make work, is then feeding labview the x value, and returning the y-value.
I get the feeling it's just a matter of data-type, as I think it should be simple using the interpolate 1d array function. Just can't figure out quite how.
One last note. I realize I'm using a function to create a graph from which I'm trying to read the function. Just simulating controling a servo to operate a valve, and correlate position and gpm.

I hate to say it, but I can't figure out what your question is from the message and screenshot you posted.
You are doing a lot of work with graphs and the Express VI's. Just barely mention something about interpolate 1-D arrays and data types, and your subject line is "relate two 1D arrays".
I'm going to take a stab at trying to figure out what you are doing. I'm going with "relate two 1-D arrays" and "interpolate 1-D arrays" and ignore anything to do with graphs.
And if I'm right, it would look something like this:
If I'm wrong, please explain more clearly.
