2 arrays to 1-D array of 2 elements

[ImpInTraining]

I have derived an X-plot (frequencies) for each point off my spectrum analyzer, and am reading the Y-trace (amplitude) ... both are an array of data.  I'm trying to get them to cooperate into a XY Plot.  When I try to bundle them then connect it to the XY Plot, it tells me that I'm trying to connect 2 arrays where its expecting 1-D array of 2 elements.  

How can I take my 2 arrays and transform them into 1-D array of 2 elements?

An XY Graph takes a cluster of two arrays.  So what you described should work. Did you use a Build Array primitive rather than Bundle.  Please post a simple example of what you have tried (using array constants or controls for the data, not your spectrum analyzer).

You have saveral choices to create valid data for an xy graph:

• A cluster of an x-array and a y-array (A plain bundle operation)
• An array of points (what you would get by placing the above bundle operation inside an autoindexing FOR loop)
• A complex array. (Simply wire the x array to RE and the x-array to IM of RE/IM to Complex and wire to the graph)

I would go with the last option 🙂

(To create multiple plots on an xy graph built a cluster array of complex arrays)

Seems to me the simplest option here is to use Index & Bundle Cluster Array.  Feed in your X and Y arrays and the output will be an array of clusters of 2 elements.

Just so happened, I have a for loop in which I am using to derive all the X points.  So if I take the output of the frequency calculation, and bundle it with the Y-trace inside the for loop, then the result should be an indexed 1-D array of 2 elements?  The lines connect now with no complaints. Still isn't drawing anything on the X-Y Plot.   But I think a definite step in the right direction - thanks.

can you post your code and the output that you expect.

The problem I'm having right now is due to instrument drivers - or rather, my not selecting the right one to give me the number of points along the entire span of Y trace apparently.  So I'm waiting assistance from the vendors on this.  If I am still having problems after I get that straightened out, I will post an example of code to help give you an idea of what I'm attempting.
