Hi,

Are you using the View Process Capability VI in the Spc_demo.llb? If so, it looks like you’re missing the subVI 2D Circular Buffer.vi in your View Process Capability VI. I have attached a screenshot of my View Process Capability VI and you might want to double-check to see if you might have accidentally deleted this subVI from the original VI.
