Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

The control limits are generally calculated as

$\mathrm{center} + k\sigma$

where the meaning of center and $\sigma$ depend on the specific control chart being drawn. The variable k is the value of the attribute "ControlLimit" associated with the line being drawn. Typically there are three lines with

If all of the samples sizes are equal, the lines are horizontal. If the sample sizes are unequal, the lines have a "stairstep" pattern. Horizontal lines have a title drawn just above the line and right-adjusted on the chart. The contents of the title is determined by the line's "Title" attribute. If the title contains the placeholder "{0}", it is replaced by the lines value. This replacement is done using String.Format.
