Brushing (analytic) in the QC Charts Module

In many situations you can use a brushing technique to explore your data graphically by assigning different point labels or temporarily removing points from the graph. Typically, you may want to use this technique in a scatterplot or scatterplot matrix. Note that a general brushing mode is available for any STATISTICA graph that can be explored in the described manner.

However, you can also apply brushing in the context of quality control. The Interactive Quality Control module includes specific brushing features that allow you to examine statistics or assign/remove causes and actions for individual samples (see Assignable Causes and Actions). You can also use this technique for excluding individual samples or ranges of samples from the computation of the control chart parameters (center line and control limits).
