Measurements outside of the spec limits represent data points that don't meet customer requirements.

I am very impressed with ChartSmartXL. I work with Excel eight hours a day and thought that I had written macros that made me efficient. The Performance Charting and Histogram macros in ChartSmartXL alone have saved me hours of work and allowed me to present data to management in a format that is meaningful.
