Location	Cause and Solution
No data to display	The grid is empty, or no properties have been selected.
Inadequacy of the Law	Change the law, or look for a mixture of populations: a histogram with two peaks is not a single distribution.
Cp is much greater than Pp	The process is veering off course. This is a management issue, not a technical capability issue.
All out-of-range points on an attribute map	Probable overdispersion in large batches: switch to a P’Laney or U’Laney plot.
Missing Capabilities	Tolerances are not specified for the characteristic.
The histogram is correct, but the map is distorted	Look at the timeline: instability isn't visible in a distribution.
