Graphical representation of the ControlChart, with the warning levels (red), set average (red), an average of the entered data points (grey), and separate data points (blue). Recalculated warning levels are green. When the mouse hovers over a blue data point, you will see more information about that entered data point. See further explanation in the table below.
Chart settings panel, the graphic display of the Control Chart can be changed; selections take place directly in the graph. The buttons can be turned on and off.
Batch count, The Batch counts bar can be unfolded. This panel lists all imported data points in chronological order of the entry date. Counts can be edited or deleted. Batch Counts which not yet participate in the calculation of a statistical Limit can be changed or deleted by the user. Modifying a Batch Count does not affect any existing NC Forms. When the old Batch Count was not conform and the new value conforms, the user must manually close the appropriate NC Form. If the new value does not conform to the limits, then a new NC Form is created. When a Batch Count is deleted, all related data is also removed. So new Statistical limits, Outliers, NC forms can automatically be removed when a Datapoint is deleted.
Statistics, The panel Statistics can be unfolded. In this panel, all the statistical data is shown as, Active form count, the average, StDev, RSD, UCL, and LCL per chart per 30 data points after the start chart of 10 or 20 data points. NC in the transition to the new chart is also visible.
