“Pen Statistics” dialog for this pen. This dialog
will display the number of points for this pen in
the plot area. For those points, the minimum,
maximum, average and standard deviation are

Spec Limits – spec limits are normally
specified by some engineering criteria. Lower
Spec Limits (LSL) and Upper Spec Limits (USL)

“Calculate” button will calculate limits that will result in CP and CPk of 1.0.
CP and CPk – When Spec Limits are entered, clicking “Calculate” will display values of
CP and CPk based on Spec Limits and the data in the current plot area.
Notes in the Plot Area – Notes are displayed as
points in the Plot Area. Note points are black circles.
When hovering the mouse pointer on or near the
point, the note information will be displayed.
Zooming in the Plot Area – You may zoom in on an area in the plot area by holding
the left mouse button down while dragging the mouse. The zoomed in area will be
outlined. The plot area will be zoomed in on as soon as the mouse button is released. If

at about 5 point intervals.
