Control charts?

[#1]

Is it possible to create statistical control charts, i.e., with upper and lower control limits calculated for a series of data points?  Thanks in advance.

If you want to know if you can add reference lines (have a look at the presentation tab in chart properties) where the position of the line is calculated (e.g. to +-3 standard deviations around the mean value of the data sample), I would say, yes, it is possible.

Have a look also at the statistical aggregation functions in QV (search for "statistical aggregation functions" in help file).
