Implements

IChartData, IVariableLimitChartData

The U chart monitors the rate of defects per unit when the inspection opportunity varies across samples. Control limits are pointwise because the Poisson standard error depends on the opportunity size. Per-point limits are stored in UpperControlLimits and LowerControlLimits.

This type contains the mathematical data and limits necessary to render a control chart, but it is a purely numerical class. It does not contain UI elements or rendering logic.
