Owning Palette: Control Charts VIs

Installed With: Statistical Process Control Toolkit

Searches Boolean input array point exceeds bound for # violations per run set to TRUE within run length. Values in the point exceeds bound array are set to TRUE if they violate some rule limit. Returns arrays with the index of each violation point and run length associated with that point. You use this VI as a generic building block in the rule checker VIs.

For example, to test the rule four out of five points above two standard errors, set # violations per run to four and run length to five, test whether each of the control chart points is greater than center line plus two standard errors, and wire resulting boolean array to point exceeds bound input.

	point exceeds bound sets each element to TRUE if point exceeds test bound.
	# violations per run is the number of violations per run length that indicate a rule has been violated.
	run length is the run length for the rule.
	violation start point is the start point of each sequence violating the rule.
	violation run length is the length of each sequence violating the rule.
