Same data type but still error

[vpn19002]

Hello,

I'm trying to connect two doubles through a bundle, creating an array with the bundles for the polar plot function.
The input requires "1D array of cluster of 2 elements".
The problem is that the error specifying that I have the wrong data type says :

You have connected two terminals of different types.

The type of the source is 1D array of cluster of 2 elements,

The type of the sink is 1D array of cluster of 2 elements.

I'm attaching pictures of the code.

It is better to attach code than pictures, but you attached neither. The best I can come up with is that you have two clusters that are not the same.

Try again. Note that you can embed pictures directly into the post.

That sentence makes absolutely no sense!!!

Works just fine here....

Hmm, I did upload both a picture and my code.. I will try it again.

Edit: I seem to be very tired today.. This was not the version with the attempted polar plot. Ill upload the right one..

I don't find the code shown in your image in your VI. Where do you try to build that plot?

I do see a VI that needs 3 stop buttons - which is higly "inefficient" and gives very bad UX…

Why do you need so many DDT wires and why do you need such a convoluted way of calculating a polynomial?

I am very new to LabVIEW.

I am taking measurements from an IR sensor do a calibration and fit a 4th degree polynomial to the curve.

Any suggestions how I would improve it?

Polynomial evaluation might be a suitable function:

Your cluster contains two elements: (1) an array on top and (2) a scalar on the bottom, each cluster elements need to have two scalars (because each point needs a pair of values!) and then you need to make an array of these clusters as I already showed.

Thank you so much!
