adding multiple Y-axis to XY graph in the program panel

[lodhi33]

Hi! 

I want to plot resistance and voltage on the same XY graph in my project. Both data traces R and V are plotted against the same X axis (current). 

I figured out how to do that in the front panel and this is how my front panel XY graph looks like: 

But what I do not understand is how do I bundle 3 traces to my XY graph in the back (programming panel)? 

I am creating a new post of my question in case I do not receive a response on the question I posted in this thread (it has been marked solved): https://forums.ni.com/t5/LabVIEW/How-to-get-a-second-y-axis-in-xy-graph/m-p/4095472?lightbox-message...

My second question was, how do I name my columns (associate string identifiers to them) when I am writing the multiple array data to a measurement (excel xls) worksheet? 

As of now, my the data is saved as "untitled" columns in my excel worksheet. I would like the column heads to show "V", "R", etc respectively... 

Thank you!

Hi! 

I read this thread as I am trying to add a new y-axis to my XY graph... 
Both my first and second Y axis need to be plotted against the same X scale and data.... 

Reading this thread I figured out how to make a 2 Y-axis, single X-axis XY graph in Labview front panel. But what I am still figuring out is how to write 3 traces of data to my XY graph in the programming/schematic of my project. 

This is how my front panel looks vs. how I program the blocks in the back (programming) panel. 

So basically, I cannot bundle three traces and send them to the IV graph... I need another way to send three traces I am trying to plot to the graph. How do I do that? 

Thank you. Any guidance at all is appreciated.

You used Bundle by Name, but didn't wire in any cluster to the top to define the names or what the cluster looks like.

Try using the regular Bundle function.

I tried the simple bundle function, not the "bundle by name" one. And I still get an error that says I have a mismatch in data types... 

The problem is that I have 3 traces, and thus my bundle output is a cluster of 3 elements, and the input of a XY graph seems to restricted to cluster of 2 elements only. 

My question is that how do people plot 2 y-axis data on an XY graph then, if the XY graph only accepts cluster of 2 elements?

Hover the mouse over the graph and select context help (CTRL+H) and you'll see that you need to bundle teh X-Y arrays as pairs, then build an array of N of those bundles..
