notch filter

Well, the Dynamic Data Type coming from the DAQ Assistant makes it impossible for us to tell what the underlying data is.  The error is clearly the result of trying to Build an array of two different datatypes.  If you hover the wiring tool cursor over the broken wire, the Context help window will tell you what is wrong.

We cannot tell how the DAQ Assistant is configured by looking at an image.

I do not recognize the filter VIs. Are they from an addon toolkit? It does not appear that you wired any input to the filters. What are you trying to filter?

Regardless, the filter output is a scalar. One data point does not make much of a graph.

Here is a unstested try:

start with some LabVIEW training, on this website, youtube, ....

Again a nice demonstation why dynamic data is of no help.
