ShowZones

This property is used to color code the chart into three zones corresponding to the number of standard deviations from the center line. The zones are defined as follows:

• The inner zone between +1 and –1 standard deviation shows in green whenever a rule is enabled that uses the 1 standard deviation limit.

• The second zone is between +1 and +2 standard deviations and between –1 and –2 standard deviations and shows in yellow. It is shown when there is a rule enabled that uses the 2 standard deviation limit (often referred to as the warning limit).

• The final outer zone is between +2 and +3 standard deviations and between –2 and –3 standard deviations and shows in red. This zone is shown when the out-of-control rule is enabled.

If one or more of the zones are not enabled, the next level zone fills in the missing zone's area. For example, if the out-of-control limit rule is the only rule applied to a chart and ShowZones is enabled, the entire area between the control limits is colored red.

This is a design-time property, and its default value is false. You cannot set this property to Null.
