When I turn off interactivity with my Axes, I get the error "Dot indexing is not supported for variables of this type."

When I uncomment the disableDefaultInteractivity I get the error "

   % Callback function executed on DAQ object ScansAvailable event
   % Check if the app object is still valid
   
   if ~isvalid(app)
       return

I get the error on the line below:

The app runs normally when it is commented out but, When I hover my mouse over the graph during live collection it lags out the plot. Sometimes it will work but then the colours on the graph will continually change. Does anyone have any suggestions for this?

Dot indexing is not supported for variables of this type.

I have also added the error message that I get. I am working off of one of the examples "Live data acquistion" but modifying its useage so the data displayed can be "calibrated" and so that in the UI the user can collect from multiple channels and pick how many.

Thanks

this has now been resolved though I am not sure how lol
